I'm in Huddersfield, West Yorkshire atm but tend to get around a lot.
Working out resonantly well, got a bit of supply ripple in the signal line and the FR of the bass control is a bit (ok, quite a bit) off. Deadline is fast approaching so trying to keep my head down!
Long Term Idea's:
Distortion circuit in series with a variable band bass circuit. (Then wired in parallel with filter circuits). Then have a separate distortion output for studio work.
Revise EQ's, make more efficient.
Separate Line In for reamping
Compressor (wouldn't know where to start tbh!)
