Marshall Drive Master with BluesBreaker Tone Control

Postby maz » February 3rd, 2020, 9:44 pm

Here's a circuit I built years ago, the Marshall Drive Master modified with a BluesBreaker Tone Control, making the pedal 3 knobs instead of 5. Everybody knows about the sound of a cranked Marshall JCM800, the Drive Master is basically a JCM 800 in a box and it is almost the same circuit than its big brother the Guv'nor, known to be a little more expensive.

I thought about sharing this modified version of the Drive Master because it sounds amazingly good, among all my gear I can count on my two hands the pedals I'm using and this is one of them. I built mine many years ago based on a layout found online, I'm not the author and I would be very glad to give him credits for the brillant idea of swapping the BluesBreaker tone control on it, this pedal is for sure a favorite of mine. You know that I don't like pedals with too much knobs but I swear its not the only reason that I love it :)

Since I can't get no information I opened it up and drew the schematic based on the pcb board inside my pedal.
