“It’s a preamp, but it’s got the biggest distortion I’ve ever heard”: Fontaines D.C.'s Carlos O'Connell reveals the secret weapon on his pedalboard – a plain box with one knob and oodles of gain'' Read the Guitar World write on the interview.

Guitarists can use the twin channel 636P2 and 500 series units via the break in/out sockets to access the exact same circuit.

Guitar pedal version of our Grampian 636 mic preamp circuit: no corners cut, all the ragged filthy glory of the Type 636 mic preamp in a handy portable unit.

As seen/heard on the pedalboards of Mason Stoops, Ben Frost, Ed O'Brien and many more...

Please note the serial plate design was changed after the photos were taken (we moved premises in 2024). This is an external cosmetic change only.

What is it? This is the hairy circuit you find in the mic preamp section of the Soundgas Type 636 - based on the Grampian Type 636 - famously used and abused by Lee Scratch Perry and Pete Townshend - and many others since. This is designed and built absolutely in the spirit of the original vintage units - no surface mount components or tone sapping DSP.

How is this version different to the Prototypes? We have kept the industrial/functional aesthetic of the prototypes with a raw casing and just the footswitch, light and knob on the top. We continually seek to improve/refine these units as we build them, but sonically the circuit is unchanged.

More information:

The unit features a balanced input via combined TRS/XLR socket, vintage germanium transistor circuitry with original Grampian specification Mic transformer, overload lamp, input impedance switch, output 3-way attenuator switch and on/off toggle footswitch. Staying true to the original design, the output is unbalanced on a ¼' jack socket and is out of phase.

Power is via a 12v external supply (included)

As with our original 636s, we have put tonal considerations ahead of all else. I was skeptical that we'd see a real benefit in using germanium transistors in the buffer section: all our original prototypes had used silicon and sounded great. However Dr Huw insisted that we build an all germanium version for comparison which proceeded to blow all the earlier versions out of the water.

The current situation regarding component shortages means that while we have secured enough vintage components to build 100 units, getting essential modern components is proving trickier with long lead times, a great deal of uncertainty and a significant outlay required. We are taking these preorders to help secure further components and to help fund the early stages of the production process.

Thank you @soundgasltd, shes a beaut...

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 noboy prepares and packs like you fine folks.
