For those who don't know this gadget, it was a lunchbox amp made famous in the late 80s by Iron Maiden and Rush.
Haven't had a chance to build it yet, but it behave rather nice on my breadboard. I tried to implement a gain pot, but my lack of knowledge gave mediocre results, plus the circuit is already well balanced and both gain options sound almost perfect.
You'll need a bipolar voltage converter (geez, it's becoming a bad habit in my layouts recently...)
Tonestack is not included, I'm working on a separate board for it.
