Optical Analog Tremolo

The all analog, light-based (optical) design of the Voyager 1 gives it vintage tone and feel, while its unique control options set it apart from the old standards.

About Voyager I

Prepare to embark on a voyage through the stars, through interstellar space and beyond, with the Voyager 1 Optical Analog Tremolo. Featuring a unique array of control functions, the Voyager 1 will propel your sonic exploration to new and exotic galaxies.

The LFO on the Voyager 1 offers a wide range of speed and depth, via the Frequency and Strength controls. A switch to select between Triangle or Square wave shapes allows you to dial in a smooth or choppier feel. The all analog, light-based (optical) design of the Voyager 1 gives it vintage tone and feel, while its control options set it apart from the old standards.

The Voyager 1 features an optional envelope control section that changes parameters based on your playing dynamics. Sensitivity is dialed to perfection with the Envelope control, and a selector switch chooses between two envelope control options. The Freq setting allows the LFO speed to increase with louder dynamics and slow back down when playing with a lighter touch. In the Fade position, a heavy hand will fade out the tremolo effect; with tremolo fading back in with light playing or sustained phrases.

A Filter control shifts between sparkle and warmth, so you can add tonal flavor to your tremolo. The Gain and Level controls not only allow you to adjust the output volume to your taste, but you can also dial in some analog overdrive to further shape your own unique and inspiring tremolo tone. Through the clear indicator jewel shines an LFO rate indicator in addition to standard bypass indicator.

The Voyager 1 is completely hand-soldered and handmade in Portland Oregon to the highest degree of quality possible. These are truly artisan crafted tone devices, sparing no detail within or without. The Voyager 1 utilizes true-bypass switching via the heaviest duty mechanical footswitch available, while your tone is transferred via quality open-frame jacks. Open one up and you’ll see an unparalleled display of craftsmanship; with immaculate hand-soldered stacked PCB’s, detailed military-spec wiring, and custom heavy-duty battery connector. On top of the USA-cast aluminum enclosure sits a durable, engraved vinyl faceplate and clear jewel indicator light. This pedal is truly built to last a lifetime.

Spaceman Voyager I – Knobs Demo

I like to use a tremolo on occasion – they’re super fun and great effect. When Spaceman came out with the Voyager I, I wanted to give it a close look. Knobs Demos – one of my favorites, put this great demo of the pedal together. If you’re not familiar with Knobs Demos, they’re not about ripping it up. They’re weird. They’re quirky. But I really like how they do it, frankly, I almost learn more from the weird notes/sounds from their videos and what the pedal actually does compared to a guy shredding.

So, this is a great optical tremolo, but a few things catch my eye. Specifically, the Gain is something really cool. I love adding the grit to the trem effect. The Fade switch is another great feature giving you the tremolo effect when the signal fades out, and more clean when you’re hitting the note hard. I love pedals that help inspire creation. I think this does just that.

Now, you need to know, Spaceman pedals aren’t cheap, but damn.. they’re worth every cent. They like to do limited runs, which does add to the excitement, and also gives you great re-sale value down the road. The Spaceman Effects Voyager I is available for $355 (silver edition), and you can purchase these directly from their website .

9 of the Best Spaceman Effects Pedals

I have mentioned the Spaceman Gemini III Fuzz several times on this blog, and have even done a specific post about switchable Germanium and Silicon fuzzes in similar territory. I feel though that I may never possess one of those - I was just too late to the party, and that offer has just long gone at anything approaching a reasonable price. Gemini IIIs appearing on Reverb.com are creeping ever nearer the £1,000 mark which is just silly money and ’unobtanium’ really as far as I am concerned. Slightly less expensive but equally elusive is the equally versatile Sputnik (I) which I also have more than an inkling for. This is also sold out, but slightly more recent, and therefore slightly less inflated at the moment in second-hand values.

Truth is that despite the bun-fight and overt ’collectors’ nature of Zak Martin’s Spaceman pedals, they mostly sound fantastic and are almost worth the effort to pin them down. Like many a boutique brand, Zak is strong in the area of Fuzzes and they form a significant part of his output. In fact I don’t know my chances of ever acquiring the fabulous Gemini III or Sputnik I - so I recently went for the equally fantastic sounding Titan II, which though lacks the uniqueness and versatility of those others.

Where I am right now, I think I’m coming more around to the Sputnik I as my principal future target - whose versatility and unique harmonic characteristics just make it one of the most phenomenal fuzzes there ever were. The larger Sputnik II separates out the Drift switch into a second footswitch and results in an over-large form-factor as far as I am concerned. My preference is always for the compact series, but I really don’t mind the mid-sized Spaceman enclosures - per the Explorer Phaser, Voyager I Tremolo and Wow Signal Fuzz Modulator.

I also include the Aphelion Harmonic Overdrive here, and the Mercury III Harmonic Boost as really decent prospects within their relevant categories. I initially had the Orion Spring Tank in the main mix, but that’s just a touch too large to easily fit in with my preferred selection, so I kind of include it as an addendum - it’s also not a pedal I’m every likely to acquire.

I really love the 1960’s NASA aesthetic too, and have a preference for standard Silver or Black enclosures and the multi-faceted LED crystals - usually in red. In any case I’ve started down the ownership path of Spaceman, and would dearly like to own at least a couple more of Zak’s fuzzes, whilst I also have a soft-spot for his Phaser and Tremolo too. I lament the fact that so many of these pedals are hermetically sealed away by collectors and pseudo art-piece-investors - while I give all my pedals a proper shift in my pedal-chain on fairly regular rotation.

I’d love to know the proportion of active to shelved Spaceman pedals, I fear that the numbers are improbably high. I wholly understand and support Zak’s wanting to regularly switch things up and be able to freely and quickly move onto other projects, it must be tedious making exactly the same pedal over and over again, so this is all quite understandable really - I just hope that we will get more similarly feature-rich and versatile compact fuzzes in the future. In the meantime, I’m going to do my damnedest to try to pin down a viable Sputnik I. To all those collectors I say please release these animals back into the wild where they may find happy homes with players who actively engage with them and play with them on a regular basis.

Note that second hand pricing can fluctuate wildly and super-rare colour runs are best left to collectors, as such pricing cannot be justified in player’s terms. I just want the standard Silver or Black versions reasonably and justifiably priced - others are welcome to engage in mock-auctions and bun-fights. Most of these pedals are already long sold-out and can only be found intermittently on the second-hand market - which means mostly Reverb.com.

Pedals are listed alphabetically by name:

Zak has a wonderful ability to deliver additional harmonic content with his pedals - which seem to give you extra layers of richness and complexity - improving the depth, dynamics and sensory dimensions of that sound. The Aphelion contains those extra bits of jangle and harmonic richness within the core of the pedal which gifts its output with an additional dose of vibrancy and liveliness.

A gorgeous organic optical phaser with just the right degree of spacey syrupiness - I would personally have preferred more of Chase Bliss Audio style chassis with a separate tap-tempo footswitch per my current 'Wombtone' phaser of choice (I also really like my Alexander Pedals La Calavera). There's no denying the lush output of this pedal - which fully recommends itself despite its somewhat slightly larger dimensions. It's a great sounding pedal which could/should though be compacted somewhat and have a couple more smart features added. I'm still tempted though - and there are a number of these still in circulation in various countries / retailers.

I've said plenty about this one already - separate Germanium and Silicon circuits that you can mix up and blend together with different levels of gain/saturation applied. A really smart and versatile fuzz - but truly out of the reach of most now. Does appear fairly regularly on Reverb.com - say roughly once every one or two months. Pricing though is edging beyond the £1,000 mark which is just too much really.

Spaceman does a few different boosts, but most seem to be of the opinion that this slightly older model is the best one yet - it sits in a nicely compact enclosure and does wonderful things to your core tone. The newer Mercury IV is also a great example, but it significantly ups the form factor. As always I have a preference for more compact enclosures - the more full featured the better - which is why I am such a fan of the more feature-rich Spaceman Fuzzes and of course Joel Korte's Chase Bliss Audio pedals - both have beautiful aesthetics too. As always, Zak's pedals have a magical way of adding harmonic richness and additional dimensions to the core guitar signal. This Boost does not quite cover all the angles my Jackson Audio Prism does, but perhaps Zak could do his own version of that with full 3-band EQ? - Here's wishing in any case. Note that relatively few of these were created and they are incredibly hard to come by nowadays.

For the longest time, the Gemini III was my most desired Spaceman Fuzz. Yet now I believe the Sputnik has become my favourite target - it has astounding harmonic richness and versatility and does some really special harmonic flutters which I just love. I've heard quite a few demos of this now, and have decided that I will put all my efforts into tracking one of these down - I'm somewhat surprised to see that no less than 18 have been sold on Reverb.com this year alone (2018) with the latest sold just a couple of days ago - don't know how I keep missing out on these? Wonderful demo above of the relatively rare Red Cyrillic Colourway Edition.

This larger deluxe update of the original Sputnik sees the Drift switch separated out to additional footswitch, the filter toggle separated into High and Low frequency boosts, and at the same time the enclosure size increases circa fourfold! I personally prefer the smaller Sputnik, although I can fully understand why Zak has created this one for the additional live-use versatility - I now just need him to shrink it back down to Chase Bliss Brothers style compactness! So let's have all that onboard a more compact Sputnik version III ! As I really can't see myself sacrificing this much pedal-board real-estate for one such pedal.

There was a Saturday special offer on this which I just had to take up, making this my first Spaceman acquired to date. I initially really wanted the Gemini III or Sputnik I and was determined to hold out for them - but have heard so many amazing demos of this, that I decided it too was definitely worth having. It's a slightly more vanilla fuzz (Silicon) than the other fuzzes mentioned here, but still has that amazing harmonic richness and sufficient versatility to make it wholly worthwhile. Just check out Gearmandude's excellent demo above.

I have several great tremolos already in the mix (including Chase Bliss Gravitas and Stone Deaf Tremotron), and were this a slightly more compact size, it would be much further up my wishlist. It nevertheless is about as feature-rich as tremolos come and sounds just as suitably wonderful as you would expect a Spaceman tremolo to sound.

This Dandy Warhol signature fuzz has been released in a few batches and takes fuzz into some new and interesting directions - more along Death By Audio lines with some frequency oscillation added into the mix. This one is also just a touch on the larger size for it to be high on my wishlist, I do though admire its output and aesthetics as is common with most Spaceman pedals. It's a nice to have, but not quite essential for me.

These have really only recently sold out - there were several in stock around the world when I did my piece on spring reverbs late last year. This is probably the neatest and most compact of the real spring-tank pedals out there, but some reviewers complain that the shorter length of springs required for this - does not convey quite the same degree of nuance as some of the larger / longer tanks/springs. This is probably the only fully / even slightly pedal-board friendly true spring reverb, but for my liking is still way too large. My current reverb pedal of choice is the Source Audio Ventris, and I have the Boss RV-500 and Strymon BigSky in reserve to give me all the reverb action I need - oh and an Eventide H9 Max. I reckon the Orion is only properly viable if you really truly have to have real spring reverb, and want it as compact as possible in the spring-tank format. So a clever pedal yes, but not quite suitable for me.

Pedal obsessives can totally get themselves twisted up chasing after Spaceman Effects pedals - if they weren't in on the original release rounds. I only came back to guitar in late 2016 so I missed pretty much most of these initial public offerings. I think you have to exercise some proper due diligence and rational thinking in the acquisition of some of these, as their prices frequently cannot be fully justified in material value. There are also a number of original Klon Centaur pedals on sale on Reverb.com for over £2,000 which is just totally insane money - just ask the maker Bill Finnegan what he thinks about it.

Zak Martin has cottoned onto the fact that most of his pedals are serially in sort of round-robin auctions, so his newish Spacelab Orbital Workshop shop on Reverb.com is a manifestation of those bun-fights - with limited run pedals going to the highest bidder. Again I don't begrudge Zak for making a decent income, but surely he does not need to persistently make the buying of his pedals akin to gladiatorial combat - and the spoils go to the man with the biggest wallet - to then sit on a shelf for the next 10 years.

There is an objet d'art quality about Spaceman Effects pedals, and the whole limited run thing makes them doubly appealing to collectors and investors, but surely these are musical instruments meant for playing? As a player, I sort of prefer the fairness of the Analog.Man waiting list approach, but I do understand that certain components do run out, and mass-manufacturing fatigue can creep in on extended product runs, so I'm not sure what I would recommend here.

I had long harboured a desire for the Gemini III, but that is now too over-inflated by my judgement - I just cannot justify spending £1,000+ on such a pedal. Yes I do have an Eventide H9 Max in a Barn3 OX9 enclosure, and a full-fat Origin Effects RevivalDrive - both of which cost more than all of the conventionally sold new Spaceman pedals, but even those multi-taskers pale in the face of the more inflated second-hand and auction-sold Spacemen.

As I sit here writing these final lines, I have already totally disqualified the Gemini III as 'unobtanium' (even if I win the lottery - probably), and I am currently trying to justify acquisition of a Sputnik I - as and when the next one materialises on Reverb.com. Looking at the Price History Chart on Reverb.com I can see that for Mint / Excellent rated condition, the lowest price so far for 2018 was £234 and the highest of £563 is the most recent sale - June 1st. I need to decide where the limit lies and whether it's already over that perceived ceiling? Decisions Decisions ...

NASA engineers discover why Voyager 1 is sending a stream of gibberish from outside our solar system

Voyager 1 has been sending a stream of garbled nonsense since November. Now NASA engineers have identified the fault and found a potential workaround.

For the past five months, the Voyager 1 spacecraft has been sending a steady stream of unreadable gibberish back to Earth. Now, NASA engineers finally know why.

The 46-year-old spacecraft sends regular radio signals as it drifts further from our solar system . But in November 2023, the signals suddenly became garbled, meaning  scientists were unable to read any of its data, and they were left mystified about the fault's origins. 

In March, NASA engineers sent a command prompt, or "poke," to the craft to get a readout from its flight data subsystem (FDS) — which packages Voyager 1's science and engineering data before beaming it back to Earth. 

After decoding the spacecraft's response, the engineers have found the source of the problem: The FDS's memory has been corrupted.

"The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn't working," NASA said in a blog post Wednesday (March 13) . "Engineers can't determine with certainty what caused the issue. Two possibilities are that the chip could have been hit by an energetic particle from space or that it simply may have worn out after 46 years."

Although it may take several months, the engineers say they can find a workaround to run the FDS without the fried chip — restoring the spacecraft's messaging output and enabling it to continue to send readable information from outside our solar system.

Launched in 1977, Voyager 1 zipped past Saturn and Jupiter in 1979 and 1980 before flying out into interstellar space in 2012. It is now recording the conditions outside of the sun's protective magnetic field , or heliosphere, which blankets our solar system.

Voyager 1 is currently more than 15 billion miles (24 billion kilometers) from Earth, and it takes 22.5 hours for any radio signal to travel from the craft to our planet.

sourloaf said: What does FSB mean?

Rusty Lugnuts said: Where are you seeing "FSB"? The closest thing I can see in the article is "FDS". In modern computers, FSB would most likely refer to the Fr0nt S1ide Bu5, though I have no idea if a system as old as Voyagers, let alone engineered so specifically, would have an FSB. (apparently I can't spell out "Fr0nt S1ide Bu5" or my post gets flagged as spam or inappropriate??)

We finally know why NASA's Voyager 1 spacecraft stopped communicating — scientists are working on a fix

The first spacecraft to explore beyond the solar system started spouting gibberish late last year. Now, NASA knows why.

NASA engineers have discovered the cause of a communications breakdown between Earth and the interstellar explorer Voyager 1. It would appear that a small portion of corrupted memory exists in one of the spacecraft's computers. 

The glitch caused Voyager 1 to send unreadable data back to Earth, and is found in the NASA spacecraft's flight data subsystem (FDS). That's the system responsible for packaging the probe's science and engineering data before the telemetry modulation unit (TMU) and radio transmitter send it back to mission control. 

The source of the issue began to reveal itself when Voyager 1 operators sent the spacecraft a "poke" on March 3, 2024. This was intended to prompt FDS to send a full memory readout back to Earth.

The readout confirmed to the NASA team that about 3% of the FDS memory had been corrupted, and that this was preventing the computer from carrying out its normal operations.

Launched in 1977, Voyager 1 became the first human-made object to leave the solar system and enter interstellar space in 2012. Voyager 2 followed its spacecraft sibling out of the solar system in 2018, and is still operational and communicating well with  Earth.

After 11 years of interstellar exploration, in Nov. 2023, Voyager 1's binary code — the computer language it uses to communicate with Earth — stopped making sense. Its 0's and 1's didn't mean anything anymore.

"Effectively, the call between the spacecraft and the Earth was still connected, but Voyager's 'voice' was replaced with a monotonous dial tone," Voyager 1's engineering team previously  told Space.com .

The team strongly suspects this glitch is the result of a single chip that's responsible for storing part of the affected portion of the FDS memory ceasing to work.

Currently, however, NASA can’t say for sure what exactly caused that particular issue. The chip could have been struck by a high-speed energetic particle from space or, after 46 years serving Voyager 1, it may simply have worn out.

—  NASA's interstellar Voyager probes get software updates beamed from 12 billion miles away

—  NASA Voyager 2 spacecraft extends its interstellar science mission for 3 more years

Voyager 1 currently sits around 15 billion miles (24 billion kilometers) from Earth, which means it takes 22.5 hours to receive a radio signal from it — and another 22.5 hours for the spacecraft to receive a response via the Deep Space Network's antennas. Solving this communication issue is thus no mean feat.

Yet, NASA scientists and engineers are optimistic they can find a way to help FDS operate normally, even without the unusable memory hardware.

Solving this issue could take weeks or even months, according to NASA — but if it is resolved, Voyager 1 should be able to resume returning science data about what lies outside the solar system.

• Classical Motion I'm afraid it might self repair. And download galactic knowledge, then decide we are a danger. And turn around. Reply

Four clas faculty researchers secure prestigious early career awards.

Continuing  an upward trend of University of Iowa faculty securing prestigious early-career grants, four investigators from the Departments of Physics and Astronomy and Computer Science have been awarded notable grant awards to advance their careers.

DeRoo, Hoadley advance space instrumentation with Nancy Grace Roman Technology Fellowships in Astrophysics for Early Career Researchers

Casey DeRoo and Keri Hoadley , both assistant professors in the Department of Physics and Astronomy, each received a Nancy Grace Roman Technology Fellowship in Astrophysics for Early Career Researchers. The NASA fellowship provides each researcher with $500,000 over two years to support their research in space-based instrumentation. 

Hoadley’s research is two-pronged. She will design and ultimately prototype a mirror-based vacuum ultraviolet polarizer, which will allow researchers to access polarized light from space below 120-nanometer wavelength. Polarizing light at such a low wavelength is crucial to building optics for NASA’s future Habitable World Observatory (HWO), the agency’s next flagship astrophysics mission after the Nancy Grace Roman Space Telescope. 

“Our vacuum ultraviolet polarizer project is meant to help set up our lab to propose to NASA for one or more follow-up technology programs, including adapting this polarizer for use in vacuum systems, duplicating it and measuring its efficiency to measure additional flavors of polarized UV light, quantifying the polarization effects introduced by UV optical components that may be used on HWO, and building an astronomical instrument to measure the polarization of UV from around massive stars and throughout star-forming regions,” said Hoadley.

In addition, Hoadley and her team will build a facility to align, calibrate, and integrate small space telescopes before flight, using a vacuum chamber and wavelengths of light typically only accessible in space, which could help the university win future small satellite and suborbital missions from NASA. 

DeRoo will work to advance diffraction gratings made with electron beams that pattern structures on a nanometer scale.   Like a prism, diffraction gratings spread out and direct light coming from stars and galaxies, allowing researchers to deduce things like the temperature, density, or composition of an astronomical object.

The fellowship will allow DeRoo to upgrade the university’s Raith

 Voyager tool, a specialized fabrication tool hosted by OVPR’s Materials Analysis, Testing and Fabrication (MATFab) facility.

“These upgrades will let us perform algorithmic patterning, which uses computer code to quickly generate the patterns to be manufactured,” DeRoo said. “This is a major innovation that should enable us to make more complex grating shapes as well as make gratings more quickly.” DeRoo added that the enhancements mean his team may be able to make diffraction gratings that allow space instrument designs that are distinctly different from those launched to date.

“For faculty who develop space-based instruments, the Nancy Grace Roman Technology Fellowship is on par with the prestige of an NSF CAREER or Department of Energy Early Career award,” said Mary Hall Reno, professor and department chair. “Our track record with the program elevates our status as a destination university for astrophysics and space physics missions.”

Uppu pursues building blocks quantum computing with NSF CAREER Award

Ravitej Uppu, assistant professor in the Department of Physics and Astronomy, received a 5-year NSF CAREER award of $550,000 to conduct research aimed at amplifying the power of quantum computing and making its application more practical. 

Uppu and his team will explore the properties of light-matter interactions at the level of a single photon interacting with a single molecule, enabling them to generate efficient and high-quality multiphoton entangled states of light. Multiphoton entangled states, in which photons become inextricably linked, are necessary for photons to serve as practical quantum interconnects, transmitting information between quantum computing units, akin to classical cluster computers. 

“ In our pursuit of secure communication, exploiting quantum properties of light is the final frontier,” said Uppu. “However, unavoidable losses that occur in optical fiber links between users can easily nullify the secure link. Our research on multiphoton entangled states is a key building block for implementing ‘quantum repeaters’ that can overcome this challenge.”

Jiang tackles real-world data issues with NSF CAREER Award

Peng Jiang, assistant professor in the Department of Computer Science, received an NSF CAREER Award that will provide $548,944 over five years to develop tools to support the use of sampling-based algorithms. 

Sampling-based algorithms reduce computing costs by processing only a random selection of a dataset, which has made them increasingly popular, but the method still faces limited efficiency. Jiang will develop a suite of tools that simplify the implementation of sampling-based algorithms and improve their efficacy across wide range of computing and big data applications.

“ A simple example of a real-world application is subgraph matching,” Jiang said. “For example, one might be interested in finding a group of people with certain connections in a social network. The use of sampling-based algorithms can significantly accelerate this process.”

In addition to providing undergraduate students the opportunity to engage with this research, Jiang also plans for the project to enhance projects in computer science courses.
