Blend between silicon & germanium Fuzz Face... best methods?

[aion]

So I've been playing around with AMZ's pickup simulator lately and had an idea. I'm wondering if I can spin up a unique approach to the classic question of combining the silicon and germanium Fuzz Face.



Two buffered pickup simulators to give a constant and predictable output impedance, then independent Fuzz Face circuits, with an output blend into the volume pot.

The germanium is on the top, silicon (1969 PNP version) on the bottom. Each has its own bias for both transistors, and their own fuzz controls.

Are there any obvious problems with this approach? Is 10k enough for the Blend control? Any other potential issues?

I had also considered either 1) using two independent volume controls instead of a blend + master volume, or 2) using a dual-ganged pot as a blend control. Each of those seemed to have their own set of issues. I also didn't want to get into opamp mixers since it felt wrong in this case, not period-correct. (pay no attention to the charge pump!)

Thanks - I remember seeing the pedal awhile back but didn't realize it had been dissected. Will have a look!

Oh believe me, about 90% of what I know was learned by typing "site:diystompboxes.com" in Google! Must have just hit the wrong combination of terms to pick up that thread.

I might not be what you want but it should give you some ideas.
