The Soundgas Type 636 preamp pedal is not just for guitarists: this mic preamp elevates any source from subtle enhancement/character to maximum sonic annihilation.
The ultimate texture/drive/fuzz/distortion whether using synths, drums, bass, or guitar - a pedal designed for studio and live use.
As seen/heard on the pedalboards of Carlos O'Connell, Mason Stoops, Ben Frost, Ed O'Brien and many more...
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 Carlos O'Connell, Mason Stoops, Ben Frost, Ed O'Brien and many more...
"The 636 is a beast used it all over the new FDC album. My favourite overdrive ever!" - Carlos O'Connell Fontaines DC
"I think you’ve really got something special with the 636s… going to be all over my recordings!! Many thanks" - Ed O’Brien (EOB/Radiohead)
"Still the best // purest distortion I’ve ever heard" - Mason Stoops
"This is the sound i have been looking for my whole life. Thank you." - Andrew Bennett
“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 up 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.
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 inch jack socket and is out of phase.
As with our original 636s, we have put tonal considerations ahead of all else. I was originally sceptical 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.
Dimensions:
185mm (7.5") x 117mm (4.75") x 80mm (3.25").
Power supply 12v centre positive 80ma draw.

“I recently had a pair of Soundgas 636P 500-series units made for me, and they’ve completely changed how I work. They add weight, tone, and a ton of color to anything that passes through them — but the real revelation is speed. Getting a drum buss together through these preamps feels like cheating.“

Sounds amazing
Sounds amazing, very special. Very dynamic. Works not only on guitars but very well on bass, keys what I prefer, drum machines :-)
It makes the sound "alive". Love it.

People like me, born in the 70s, haven't had much chance to hear a sound like this. I was lucky enough to experiment with tape echos in my teens, relics of old relatives. Those machines made a difference to the sound even before the echo was on. Here, we here a preamp like no other which turns even the most feeble signal into a monster. It's an "overdrive" you can't get anywhere else, it's analogue steroids, and it's in fact inexplicable. It sounds like nothing else.

Game changer
Like a pultec eqp1a this is a real game changer unit like you wanna run every tracks into it. The sound become way much warmer and present so easily. You can push hard into it and still super musical and pleasant.
Best purchase I did so far lately

An Interesting Flavor
Very interesting preamp - lots of grit of course. Sounds great on guitar as you would expect, but so far I like it most on chorus vocals to get some extra focus and energy.
I tried it on bass, (Low Impedance Break in/out > DI>Padded 5116-B), but I found the curve from clean(ish) to break up to be a little too fast so that the peaks were quite distorted while the body of the notes were not, even at around 10 o'clock with a passive bass. Hind sight, could be that it was hitting the subsequent preamp too hard. This thing adds a LOT of giddyup to the signal. Interested to try it the other way (Bass DI>636-P), but haven't gotten around to it yet.
One of my favorite parts of owning a piece like this is the pleasant surprises you get through experimentation. Sometimes you'll crank out an entire track without even noticing it.
Great work, SoundGas!

Fantastic Preamp from character to grit
I was exdcited when these were released for the 500 series rack, and got even more excited when I started using it. Great for Black Ark-like flavours, giving grit and dimension to electronic instruments, or as a deep and stromg Bass DI.
The signalflow and I/O also makes it easy to use it as a preamp in fromt of a guitar amp. It sounds special as a mic pre on drums and guitars and vocals.
I love having character gear in the rack, to use for very specific sounds or to use for those special occassions. This is all that, but somehow an all around flexible tool at the same time, that will see constant use in all kinds of sessions.

Really rich and cackling grind when cranked- this pedal has a shimmering rasp and low mid bark- great pedal

Efforts are rewarded
This is a preamp like no other. Yes, it does take a while to become familiar with the way it responds. Yes, some of the most desirable settings are located at quite extreme pit settings, both high and low. And, yes it is all definitely worth the effort. This isn’t the most flexible preamp you’ll ever use. There will be applications for which it won’t be your first choice. But, there will a myriad of occasions where this plain looking little box will add so much magic and sparkle to your recordings that you’ll be unable to stop smiling for a week. In the age of computer recording, as we all battle to reinsert the ‘soul’ of the music we know got lost, the 636P2 is the antidote to many of your ills. It’s not cheap, it’s not perfect, but, it is a thing of genuine beauty, that rewards effort and makes things ‘better’. What more could you want?

The missing link - couldn’t be happier with it, it sounds incredible and adds enormous flexibility to my recording chain. Absolutely love it.

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.
