*Soundgas LFOmo Auction

Brand: soundgas

Categories: AUCTIONS

Auction in support the DEC Turkey/Syria Earthquake Appeal. One of three unique custom LFOmos created by the Soundgas team.

This item is for sale by auction.


The Soundgas LFOmo is the ultimate utility companion to your synths, guitar pedals, rack gear. Works with pretty much anything with cv or expression pedal input. 

We’re auctioning three unique LFOmos each one hand decorated by one of team: Chris (LFOmo designer), Dec and Tony. All proceeds from the sale will be donated to the DEC Turkey/Syria Earthquake Appeal.


A note about bid extensions / overtime in auctions: if a bid is placed in the final 5 minutes of the auction, the end time will be extended for a further 5 minutes. Read more about this…


Nearly a year in development, the LFOmo is designed to massively expand the sonic possibilities of synths, guitar pedals, modular synths and studio gear.

  • We have built two preproduction runs due to ship out from mid March.
  • If you don’t want to bid on a custom version you can buy a regular one.
  • It works with pretty much anything that has an external cv or expression pedal input*.
  • Originally designed to “upgrade” a Juno-60, but ended up going way beyond that remit.
  • If you own a synth or two, and/or a couple of pedals with cv or expression pedal inputs, you need one of these.

Read the new blog with more LFOmo-info and a directory of video demos.


What is it? LFOmo is an external syncable super-flexible LFO with two banks of eight waveforms, clock in/out with various clock divide/tempo variation options. See the photos of the prototype pedal design to get a feel for what is included.

Some years back we discussed working with Nils Frahm to build an external unit that would enhance and expand the capabilities of Roland Juno 6/60 along the same lines as the units he uses, but that never happened. LFOmo was initially (in my head anyway) that unit, but as we developed it, we realised it was capable of a great deal else besides.

What does it work with? Analogue synths come alive when paired with LFOmo: my humble Korg Polysix became something else entirely. We have extensively tested it with Roland Juno 6/60 to great effect. Any synth with a cv or expression pedal input – the list is extremely long. Any rack gear with external cv input (works very well with Marshall Time Modulator for example). Modular synths. And of course the many guitar pedals which have cv or expression pedal inputs – we’ve been testing with Strymon and Chase Bliss pedals and getting somewhat giddy at the results. You can clock it from your DAW/drum machine/modular. Or not: allow the LFOmo to run free and off grid…

How do I use it? Don’t be daunted. Experiment. Try stuff. If it works/sounds great, it’s good. If not, move on, try something else. So far (still Tony writing this) I have been unable to break anything by trying different things. Chris plugged the LFOmo cv out into the Midi in of my Chase Bliss Gen Loss MkII and it was wild. At its simplest, plug the LFOmo cv output into a (synth) cv filter input (eg Roland Juno 6/60, Korg Monopoly/Polysix) and play with the settings. The same goes for guitar pedals or studio effects. What we have found is that extensive testing of every feature on each synth/pedal/effect is tricky to focus on – we keep discovering great sounds/effects and just get lost in playing/recording. Clock it from your synth/DAW/modular/drum machine and play with the clock divide function.

Is it just for vintage synths? No. It works with anything that has a cv or expression pedal input. Guitar pedals abound with expression inputs: it’s wild with them.

Do I need a manual to use it? Tony here: I’ve been using the various iterations of this unit for nearly a year now and have not needed a manual so far – and I’m not particularly technical or cv savvy. It’s pretty simple in operation but capable of coaxing the wildest effects/sounds out of the humblest of gear. I’ve taken the feed out of LFOmo and split it into multiple units to great effect.  Like modular synths, it rewards experimentation, but unlike modular, you do not need to be a scientist/boffin/synthnerd to use it!

Is there a manual? Not at this point. There will be, but this initial run is for those trailblazers who want to dive right in and not RTFM. There will be a video guide, but it’s not ready yet.

How is it powered? Standard 9v internal battery that will last a long time (please don’t leave it switched on for days to test this) or an external centre positive power supply (same as Moogerfooger etc – the opposite polarity to standard Boss type pedal psus).

Is it a guitar pedal? Not strictly speaking, but it works very well with many guitar effects pedals.

Do I need more than one? Not initially, but we have realised that we’d like at least two ourselves – if only to be able to clock a second LFOmo from the first and come up with some batshit crazy patterns. Or one for the pedalboard, one (or two) for the synth rack…

*As far as we have tested – it has been designed to work with most gear with a control input.

"Soundgas provided the absolutely top service in terms of item quality as well as service and communication. Shipping was fast, packing was top notch. These people deserve the best reputation they already have. Many many thanks, guys."

Dupille Luc

I have been buying vintage stuff for a long time from resellers/stores/techs. I've never been so surprised and pleased after opening! Just received a Roland RE-201 and VX55 mixer, they look and sound amazing! Thanks to Tony/Declan for the service and the Soundgas team will be back!

Dong Yun Seok

“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."

Josh Lloyd-Watson & Tom McFarland - Jungle

"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."

Koko Hiras

As good as it gets. Tony, Dec and team have been incredible, prompt communication, great advice and outstanding service. It really felt like my Polysix came from a loving home.

Ben Parm

Purchased a Juno-60 and it works beautifully. Having gotten one teched before, I knew it was worth paying a premium to get it future proofed and Soundgas does just that. Shipped professionally from the UK to USA. Appreciate their expertise and professional demeanor!

Eric Cullen

"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."

Ben Van Vlissingen

"DREAM. COME. TRUE. My music has taken me around the world a few times...and if you are like me and absolutely adore vintage gear...Soundgas is the stuff of LEGENDS. It's the shop that people like us search for our whole lives- fantastic and rare selections, and the technical know-how to repair and or mod these vintage items to get them into shape to flow with your modern setup."

Tom Gossin

"Engaging with old gear can sometimes be filled with a lot of uncertainty, and I can't imagine what more could be done to reduce this aspect of it on top of the service you provide. Really phenomenal and I couldn't be happier."

Stephen Voinea

“I purchased a completely overhauled vintage valve Binson Echorec 2 T7E modified with varispeed, wet-only output, and a new paint job from Soundgas in early 2018. Tony and his team did an amazing job during every step of the purchase”

Matt Morton

"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."

Matthew Herbert

Grabbed a Roland RE-201 (early edition killer pre-amp) and Roland DC-50. Absolutely STUNNING. These guys truly live up to the hype. They are meticulous in caring for the gear. Also, I have a few guitar pedal and plug-in emulations of tape-echo sounds and after plugging in the real unit I can't tell you how insane the difference is. It is incredible. Especially that tone from the early pre-amp! I am totally amazed. I am in heaven :) They made it safely to Nashville from the UK and were packed really really well! Thank you so much!! Worth every penny.

Chance Allen

Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.

Tom Johnston

"Still in shock! Can not believe how good the seller is. This product was inspected, and shipped from the UK to the USA quicker than orders from my home state. Highly recommend these guys."

Thomas Tedesco

“I have bought two Moog synths from Soundgas over the past year, and I cannot say enough wonderful things about their selection of vintage products, the level of service, diligent responses to email, and expedient shipping with copious protective packaging. Soundgas is an impressive operation. My synths also sound amazing! These folks have made my vintage keyboard dreams come true in short order!”

J Yates

“If not a new language, then at least a very challenging, old dialect that will take me some time to assimilate. I’ve been waiting a long time for the challenge. Thank you @soundgasltd, she’s a beaut...and nobody prepares and packs like you fine folks.”

Justin Meldal-Johnsen

"Soundgas has an unbelievable selection of the cool, old stuff that’s hard to find. Tony knows his stuff and goes out of his way to make sure the transaction is a smooth one. Thanks guys!"

Tucker Martine - Flora Recording

"Yes, sure, you can find a Space Echo on eBay, but you won’t find one like this — that’s certain. I am so pleased with my decision to buy from Soundgas, and suggest you stop your search now and just send them a message. You will undoubtedly find yourself writing an ecstatic review about yours in short time."

Ben Evolo

“If you are a vintage audio gear head then this is the place you have been looking for all your life. Pretty much any piece of classic or obscure kit that you are after is available here... But the clincher for me is that the gear they sell has been restored by their top techs (unless otherwise noted) which is really very important when dealing with, for example, synths from 30 years ago.”

Lincoln Barrett / High Contrast

“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”

David Wrench

"Soundgas offer a great service, sourcing esoteric gear that works great."

Tom Rowlands - Chemical Brothers

"808 is up and running. It’s hard to stop playing it. Like even to eat. Extending testing is quality control and the quality of your stuff combined with customer service is one of the reasons Soundgas is so successful in my opinion."

Brett R

"When you are spending big money of vintage gear it's nice to have the confidence of impeccable service, sales and support... some of the best in the industry! Impeccable people, incredible equipment… my poor poor fiancé"

James DLR - Sofa Sound/Metalheadz

“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”

Julius Bonson

“The perfect place to hear, learn about and then buy your most wanted piece of vintage music gear! I've not only managed to buy a rare piece of equipment I really wanted, but I have the guarantee it's been serviced, and I got it from people who are clearly passionate and knowledgeable about what they do, as well as super friendly and responsive by email. Thoroughly recommended!”

Colleen / Cécile Schott

Just wanted to say thank you so much for your pinch roller and echo tape. I've had a space echo for years, been sent to a shop in NYC and it never worked quite right. After installing the roller and tape, my echo works like a dream. Really incredible expertise you all have! Thank you.

Andrew Potter

"The packing job to get it over to the US was superb, and the sound and performance of my Space Echo exceeds all of my expectations. I hope to do business with Soundgas again in the future. Many thanks!”

Rhett Daily

"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."
