Product Description

We began building these in 2019 with the intention of making a run of ten or so units. Demand outstripped our expectations so we built more. However production is now ceasing to focus on new Soundgas products. There is one unit remaining. We have no plans to build any more now. These are the best units we have produced and are set to be future classics.

Hand-built in limited numbers incorporating vintage components, this is the only Grampian 636 inspired circuit available today that uses the correct microphone transformers and circuitry for an authentic sound. The Soundgas Type 636 features all the hairy sonic goodness of the original units with greater consistency, lower noise and more low end in a convenient and reliable rackmount unit.

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 NOS vintage/original parts where essential for an authentic sound. For the 2023 Soundgas Type 636 we are using a carefully selected new spring tank that for greater consistency and reliability which is proving very popular here. We've been building these for approaching four years now years and the design has evolved with each build, incorporating incremental improvements, the pinnacle of which is the 2023 Type 636.

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-invigoration of the 636 circuit does not extend to modern corner-cutting - far from it - the attention to detail evokes a bygone era when recording equipment was hand-built with care. The circuit boards have been lovingly hand-etched and deliver all the wild tones and textures without the extraneous noise and hiss of a neglected original. We only hand select and match NOS vintage British Germanium transistors for the circuit (this takes a great deal of time and expense to do right, but the sound is unmistakably glorious as a result). No corners are cut, no expense spared to deliver sonic excellence.

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 by 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.

Over the past four years, Soundgas 636s have been helping shape the sound of some of the world's most iconic artists, engineers/producers and studios. 636 series owners include:

Richie Hawtin, Ben Frost, Tom Rowlands (Chemical Brothers), John McBride (Blackbird Studios), Paul Epworth (The Church), Ed O'Brien, Chris Messina (April Base Studios/Bon Iver), Frank Wiedemann (Innervisions/Ame), Al Doyle (Hot Chip/LCD Soundsystem), John Mayer, Arthur Fielder, Shonky, Maribou State, El P (Run The Jewels), Mike D.

Very limited production - handbuilt entirely from scratch in our workshops in Crich, England.
