Clone of a famous purple Marshall-in-a-Box pedal. Dial up some crazy high-gain crank in a very small package.
Volume control does what it says, Frequency offers a good range of filtering to tune the tone just-so. Unfortunately the Gain control could just as well be a toggle switch. You'll get very little change across most of the turn, then a shed-load of gain in the last few degrees. This is a design flaw in the original, but after much experimentation it has proved impossible to make much of an improvement. Embrace it or move along.
Another warning - this is not a quiet circuit. Some noise may be present if playing gently or with the guitar volume wound back. 'Tis the nature of the beast. Who's going to play this quietly though? This is hard-rock/metal through and through.
Designed for vertical-pin board-mounted pots (which have round shafts) for minimal wiring and easy enclosure mounting. Feel free to wire up 'normal' pots if you prefer.
Note: if you go for vertical-mount pots we'll supply a reverse-log 1K for the gain control. This gives a much better sweep than the standard 1K Linear pot of the original. Unforunately we don't have 1K reverse log in the standard wired pot so you'll be stuck with 1KB.
