...but I'm not totally finished, as I can't reconcile what the pictures seem to show with how the gain pot supposedly operates.
Please have a look at the circuit portion between Q1-gain pot-Q2 in these excellent pics, diagrams and parts list to see what you think -nocentelli wrote:Very interesting: The gain pot lug one appears (in the googledrive diagram2) to be wired directly to ground, which should short the input to Q2 to ground and give silence (which is why I asked if gain on zero muted it). The best way to replicate what you describe is simply to lift lug 1 of the gain pot from ground, which actually sounds very nice.ziotasgiorgos wrote: The gain knob behaves weird. It's not exactly a "gain" knob. It's a "voicing" knob.
Fully CCW it sounds like a distorted VOX and fully CW like a Distorted Marshall. There is no 0 setting!!!

Also, the version documented is clearly different to the version being so ably demonstrated since there doesn't appear to be a gain switch.
