SOLA SOUND: Tone Bender MKII Professional, 0.15″ Vero

Not strictly my layout, as this is a copy of the original Sola Sound Tone Bender MKII board.  

This is a little different to most MKII schematics, as it has a 10k resistor from base to ground on Q1, and a 47k on the collector of Q2.  I’ve read that this is best for leaky OC75 transistors (which I have a few of).  The 100k bias resistors were mainly used for OC81s.
