Ok, one transistor. Probably that thing I thought, we thought, it was a metal can old transistor was maybe a cap? Maybe the previous version was different? Where were all those resistors?!

It will be nice if that guy could read the label on the transistors and the caps.

Q1: Unknown.

Pot Grit: ?
Pot Volume: ?

C1: Red Wima ?
C2: Electrolytic cap ?
C3: (6800J). Maybe this kind of caps are rather small, so it could be 6800pF (6.8nF)
C4: Monoholityc cercamic cap ?
C5-ALT: 0.0022k (2.2nF)
C6-ALT: 0.047k (47nF). It's updown, and the just half label is visbilbe.
C7: Silver cap ?

Glass red diodes: 1N4148 (or 1N914)
Glass clear diodes: I have some russian germanium D9E that looks like that.
Black diode: 1N400X.

The upper footswitch si the Boost, the downer one is the bypass.
The upper toggle switch is Guitar/Bass, the downer one Bright/Wooly.

I have to do some effort to find the resistors value. I think on the footswitch board we can find the LED resistors. On the Grit Footswitch there's a second resistors, it should be the mod, maybe setting a fixed resistor to replace the pot.
