Built it and it sounds really good!
Thanks Alex for the layout It's a great update to the old Bosstone. Sound quite brutal at times with that 330nF input cap.
If you roll bach the gain pot and turn the bias clockwise you get some really cool octave down tones that tracks surprisngly well across the neck.
Glad it worked! I was pleased with the heavy sounds you could get with just a few mods. Thanks for the octave type tip. I'm boxing mine up too, since I know it'll get a lot of use. The original has some pretty cool graphics.
