TL;DR: Hand-built in Derbyshire by the team behind the Soundgas Type 636P series, the Type G is a limited-edition analogue germanium preamp pedal inspired by the finest early echo and console circuits. It delivers the open, harmonically rich Soundgas tone: from clean boost to full saturation, for guitar, bass, synths, or studio use.

The Soundgas Type G is our latest hand-built preamp pedal, designed and built in Derbyshire by the team who build the Soundgas Type 636P series.

Drawing on years of experience restoring and analysing vintage preamps, including those in our modified Roland Space Echoes and classic studio consoles, the Type G captures that unmistakable Soundgas feel: open, harmonically rich, and dynamic. This is not a clone, rather a new design rooted in the preamps we know and love.

Built around selected vintage germanium transistors, the circuit has been tuned for clarity with character - enhancing the tone of your instrument while delivering the natural warmth, depth, and saturation that define the 636 lineage.

Three simple controls - Gain, Tone, and Volume - unlock a wide range of sounds: from clear, chiming definition to hefty, thick, overdriven wall-of-amps textures, but at home-friendly levels.

The result is a deceptively simple analogue tool with myriad uses that offers boost, drive, or classic vintage preamp warmth wherever it’s needed.

The Type G is hand-assembled, calibrated, and tested in our Derbyshire workshop and produced in very limited numbers. There’s no digital modelling or emulation, just a genuine Soundgas original analogue circuit, discrete, characterful, and designed to inspire.

What are the differences between a 636P and the Type G? 

Tony replies: The 636P is a full featured mic preamp circuit with multiple germanium transistors and an input transformer: it is complex and extremely picky about components to achieve its incredible sound. Expensive and time consuming to build and was never really meant to be a guitar pedal - it just turned out to be exceptional with guitar. The Type G has been designed as a guitar pedal first and foremost (but still sounds great with other sources) so we've been able to design it from the ground up with this in mind. We've wanted to create a guitar pedal drawing on the 636 heritage since the very first Soundgas Type 636 Spring Reverbs were built but have never been happy with the tonal compromises we had to make to reduce the circuitry/cost. It was only when we started again, with a fresh approach (and no longer wedded to just the 636 circuit) that the magic unfolded. The Type G is something new and we are very excited to hear what people do with theirs.

I already have a 636P - do I need a Type G?  

The short answer is yes. They are very different units and work well separately or together. I’m using the G into my P with great results. The G is sonically very versatile and you can sculpt a wide range of tones using the Volume, Tone and Gain controls. Think of the P as enhancing the tone of what you put into it (with of course the option to drive it into monstrous saturation/fuzz), and the G as something that can (to my ears anyway) quickly open up a world of classic guitar tones/textures. I’ve found I can get immense driven big valve amp sounds at very low levels on my low wattage home amp. We’ll be doing a range of demos soon, but Prototype #2 that you see here left us suddenly for some very real world testing with one of our favourite customers (who loves the 636P). He’s reported back that it’s going straight on his board for a run of gigs next month, so we’ll have to wait a little longer while Ryan builds us another prototype to demo!
