Screen Shot 2022 08 06 at 12.19.15 pm 06a8c1cf556a

Yet to build this myself, I quite like the idea behind this – I am partial to anything with bass / mid/high controls for guitar and a germanium transistor.  Bonus points for also including a discrete op-amp, which I’ve been playing with lately. Before I looked at the schematic for this, I was playing around with modding a Boss Blues … Read more

Suggested as a favourite along with the Wampler Plexi-Drive by Ding on another post, so thought I would take a look at the Ramble FX Marvel Drive 2.2 They’re clearly going for a Marshall vibe, and they have some success capturing this through the sound of the video demos.

BENSON: Preamp, Mojo Vero Layout (with 1m bass pot mod)

BENSON Preamp 1m bass vero mojo layout v1a 3865a14ed596

The Benson Preamp is pretty popular, but 2M pots are hard to find.  This is a modded vero layout using a 1M bass pot.  To make this change and keep the same frequency response, resistances are halved, capacitance is doubled.  Note that the Drive pot value also had to be halved. I’ll add a regular size … Read more
