Sandblaster Fuzz

Very cool stuff here. Nice overdrive tones. Very low gain fuzz if any on my build. But it sounds good. It reminds me of a highly tweakable Range Master. It's got a germanium feel but its silicon. I'm having a fun time with it. The 3 trim pots on the inside are for biasing and I set the middle position a little under bias to get that starved battery feeling to it. The up and down settings on the toggle and not wildly different sounding but enough that it gives you some options. Aside from that it's built to the silkscreen. I don't know if I would classify it as a "Fuzz Drive", but it could fall into that category.

Overall, I dig it. Will probably add a demo for it at some point.

What's the best way to measure voltage for each one of points?

Measure at the center lug of the bias toggle switch for all three settings.

Set the bias for the Middle position first.
