Hi,

I will have this pedal for a few days.

Are all values, it is only to make the schematic and go over how it works.

Thanks for the pics and trace! Looks like a straight clone of the Dan Armstrong Green Ringer with a 100pF cap to ground at the input.

A green ringer in other words,
I'm working on the same circuit right now and I found that Ge transistors do sound better.
Also tried with a shottky and it was already better than the standard 1n4148.

I observed that it gives a nice sound with only one diode too, it sounds fuller, but as a result the octave effect is much weaker.
I'm installing a LED-LDR circuit to control this two configurations.

I see it as having the soul of the Green Ringer but it is quite different in some things.

Could you do a layout for Friday? it would be more a octave-friday than a Fuzz Friday :D

I really think it sounds much better than the Green Ringer, the octave is much more defined anywhere in the fret board and is a bit more "organic" sound

I've seem some Green Ringers with different values for the resistors on Q1, but other than that, looks like a regular green Ringer.
