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.
We have enough components for five more machines. Delivery time TBC.
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.
