PRICE: £23,500.00 EX VAT (£28,200.00 INC VAT)



A ‘space’ saving version of the original Colossus classic. Ideal for those with a little less spare studio space, or perhaps with very restricted access for installation.

Brand new synth which will be completed to order. We are authorised dealers.


Brand new Analogue Solutions AS200 Colossus ‘Slim’ for sale.

Soundgas are proud to be acting as agents for the Colossus, and now it’s new svelte sibling. Both versions are available – see the original ‘Colossal’ Colossus.

More spec below on how it differs from the original, but essentially it’s a ‘space’ saving version of the original Colossus classic. Ideal for those with a little less spare studio space, or perhaps with very restricted access for installation.

AS200 compromises very little to obtain its smaller footprint – over 50% smaller. The unit is a little taller than the classic. It takes some of the features found in the classic’s horizontal console, and flips them vertical.

> Scroll down for video we took of the original Colossus in action at Synthfest, plus Tony managed to grab an interview with designer Tom Carpenter.

> Available now. Lead time on orders is currently only 2-3 months on payment of deposit.

> The price – £23500 – is excluding crating, shipping and any applicable taxes. A 25% deposit is required to get on the order list.

We said this about the Colussus when it first appeared, and all of it still holds true:

This is a once in a generation (semicentennial?) opportunity to purchase an instrument that is not only of epic ambition, but is also an astonishing feat of engineering and craftsmanship. In the grand tradition of synthesizer pioneers, Tom Carpenter has brought the Colossus into being through sheer force of will: a testament to his passion and vision.

Tom Carpenter has realised a lifelong dream and created what may well turn out to be the synth of the decade: the aptly-titled ‘Colossus’. Bearing more than a passing resemblance to the fabled and legendary EMS Synthi 100, this stunning synth is a staggering technical achievement of towering proportions.

Superlatives abound when referring to this analogue behemoth which, in spite of the obvious design and layout references, Tom stresses is not a re-creation of the EMS, but a design drawn from his many years’ experience and Analogue Solutions pedigree. The design and spec is of epic scale and includes: 12 VCO, 2 LFOs (so possible total of 16 LFOs using VCOs); 8 Filters with serial VCAs; Sample & Hold; twin patch matrix panels, joysticks, spring reverbs, ring modulators, 32 step analogue sequencers. No midi or usb: this is an analogue monster that makes my beloved Synthi AKS seem a little underwhelming. It now sits firmly at the top of my Christmas wish-list.

Appearances can be deceiving: the Colossus is not a Synthi 100 clone and circuits are all Analogue Solutions’ designs. Aesthetic and ergonomic design inspiration is drawn from the fabled EMS Synthi 100, however, no circuit from the Synthi has been cloned or copied. AS have drawn on favourite circuit designs from their 25 year history of synth-building and incorporated aspects of Polymath, Telemark and Vostok in the Colossus. Like Peter Zinovieff with EMS, only an enthusiast-led company would dare to strap on such wings and stand on the precipice of commercial endeavour with such an undertaking. The Colossus is built to a specification and hang the expense. Only ‘around 200’ are expected to be produced. We applaud Tom and the team at Analogue Solutions – this is a new chapter in the history of glorious British synthesizer design.


From Analogue Solutions:

AS200 compromises very little to obtain its smaller footprint – over 50% smaller. The unit is a little taller than the classic. It takes some of the features found in the classic’s horizontal console, and flips them vertical.

Gains over the Classic version:

  • Smaller foot print – over 50%
  • More mixer inputs.
  • Fully independent pin matrices (not internally wired to anything).
  • Lower price tag.

Classic Gains over the Slim:

  • Larger pin matrices.,
  • Touch keyboards.

And the rest of this is the same as the original Colossus info:

It is more than a powerful analogue ‘workstation’ – it is also art, architecture, exquisite studio furniture.

Design inspiration is of course from the 1970’s EMS Synthi 100, however, no circuit from the Synthi has been cloned or copied. We prefer to make our own designs. We have chosen some of our favourite circuits from our own large back catalogue synths such as Polymath, Telemark and Vostok.

Colossus is not a Synthi 100 clone – all circuits are non-EMS, Analogue Solutions’ design.

The original Synthi was so large it wouldn’t fit through a standard doorway. We didn’t make that mistake but don’t underestimate it’s size. It will be prominent in your studio, or art gallery!

All the voice and modulation circuits are of course 100% analogue. We purposely steered away from digital, it doesn’t have MIDI or USB (there are plenty of MIDI converter boxes out there should you need that facility). This wasn’t designed to be the solution to your modern digital studio but rather a serious analogue power house of sound. There are of course digital elements to the sequencer control – that is unavoidable – even classic analogue sequencers like the ARP sequencer using digital logic chips. In fact the Synthi 100 features a digital sequencer.

This synth is purely for those who want it just as it was in the 1970s – but new with parts still in production.

Colossus is large scale, featuring large knobs that control metal shaft potentiometers. VCOs have multi-turn verniers. The two enormous pin matrix panels dominate the horizontal panels – these are incredibly expensive Swiss made broadcast quality signal routers – 1 for CV and 1 for Audio.

There are two spring reverbs, step sequencers, moving coil meters, joysticks and so much more. An immense expanse of jack sockets for additional patching within or without the system.

There are no gimmicks – this is pure synthesiser. A huge sound enclosed in a solid metal case wrapped in solid hardwood. No expense has been spared to bring this incredible machine to life.Synthesisers like this only come around once in a decade, or possibly a generation.


VCO Panel

  • 12 x Analogue VCO (/LFO)s.
  • Four waveforms, Pulse Width, Sync, Sub Osc. Ability to go down to low frequencies. Precision control using high quality multi-turn vernier dials.

  • Multiple.
  • VCOs can be used as LFOs. So Colossus has in fact a potential total of 16 LFOs!
  • Each of the 8 VCFs have VCAs hard wired inline, so these plus the individual VCAs means there are in fact a total of 12 VCAs!

Filter Panel

  • 2x Ring Modulators.
  • 2 Voltage Slew Generators.
  • 4x ADSR with repeat and hold-repeat feature.

Sequencer Panel

  • 4x large signal level meters, backlit.

Touch Panel

  • 6 channel stereo audio mixer with level, pan and mute.
  • 2x Joystick Controllers.
  • 2x Touch Keyboards with digital note sequencers.


  • 2x Broadcast quality CV and Audio Pin Matrix panels

Jack Socket Patch Panels

  • 4x minijack patch panels – providing I/O from all circuits.



Outside of UK it would need to be crated on a pallet, then freighted.

Crate & packing cost estimated at £350 exc. tax. (for UK orders collection is possible – delivery: maybe).

Shipping depends on destination. Typically around £1250 to USA. Less for Mainland Europe.

If you aren’t too far from Calais there maybe other options.

Synthfest UK 2019 – The Soundgas Report

We all had a gas at Synthfest 2019 in Sheffield. This is our report including video of the mighty Colossus in action plus an interview with...

PUBLISHED: 9th Oct 2019



"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

"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

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

Tom Rowlands - Chemical Brothers

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

"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

“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

“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

"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

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

"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

“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

"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

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

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

"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."

Hallam Kite

“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 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

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

Julius Bonson

"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

“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

"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

"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

"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

"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

“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

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

"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."
