The Soundgas Type 636 brings the hallowed Grampian Type 636 Spring Reverb design into the 21st century; an authentic future studio classic.
Hand-built in limited numbers from vintage parts, this unit features all the hairy sonic goodness of the originals with less noise and more low end in a convenient and reliable rackmount unit.
AUTUMN/FALL PRODUCTION 2020: preorders open for the final ten units – order via this listing or email to pay a £1k deposit.
We have secured enough vintage components for another ten units which will be our final build of 2020 with no further production planned.
Photos on this listing are now of the full production prototype – this is what you will receive. Sexy as hell, frankly.
The Soundgas Type 636 Spring Reverb brings the hallowed Grampian Type 636 into the 21st century. Whether you seek the ultimate dub reverb, the meatiest distortion, or achingly beautiful organic textures, the Type 636 has it by the truckload.
These units are hand-built to order in very limited numbers using many vintage/original parts for an authentic sound.
The design is as faithful to the original as possible and delivers all the hairy sonic joy of the originals. Dr Huw’s 21st century re-imagining does not mean corners cut – far from it – the attention to detail evokes a bygone era when gear was hand-built with care. The circuit boards have been lovingly crafted and deliver all the wild tones and textures with none of the extraneous noise and hiss of a neglected original. Wherever possible, we are using period correct parts for absolute authenticity.
The Soundgas Type 636 is a Grampian with less noise, more low end and greater reliability, designed with the benefit of hindsight and decades of experience with the originals. We’ve taken the best from various eras of 636s and brought them together with a studio sensibility – accentuating exactly the flaws and foibles of the design that are so beloved of today’s users. Individual Grampian 636s all have unique sonic signatures due to age and construction and each hand-built Soundgas Type 636 will be a unique piece. We keep two Grampians in the Soundgas Studio because they have quite distinct characters (one has an original Gibbs tank, the other a later Accutronics tank, but the circuit designs are quite different also).
A true studio classic designed and built with love and attention to detail for today’s musicians and producers.
PREORDER INFORMATION: Preorders are open for this build – you can either pay a £1000 deposit or in full – please email if you wish to pay a deposit.

“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.”
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.
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!
"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!”
“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.”
"Soundgas offer a great service, sourcing esoteric gear that works great."
"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!"
"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."
“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!”
“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”
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!
"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
"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."
“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.”
"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."
"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."
"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."
Fantastic. From initial contact to the product landing at my door the service provided was outstanding. Safe and secure shipping, quality serviced product.
"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."
“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”
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.
"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"
“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."
“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!”
