We are planning to build a short run in Autumn 2025 before ending production for the foreseeable future. Place your preorder now to reserve your unit.

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

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.

PRODUCT INFORMATION

Limited units remaining before we cease production in spring 2025.

The Soundgas Type 636 in guitar pedal form. No corners cut, all the ragged filthy glory of the Grampian/Soundgas 636 mic preamp on your pedalboard.

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? Photos are of the latest version. Based on feedback and our own testing of the original units, we have moved the input and output sockets to the rear of the box and added a three position attenuation switch on the output. This to tame the massive amount of gain produced when dialling in maximum overdrive/filth: now you can have all the dirt without overloading your amp/ears/signal chain. We have kept the industrial/functional aesthetic of the prototypes with a raw casing and just the footswitch, light and knob on the top.

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.
