So, jwar, got any suggestions for improvement on the Dirty Doper?
Seriously, I'm all ears.
1) Right now the big structural change is going to be PCB mounted switches (I haven't decided on pots yet), I've railed against PCB mount panel controls for years.. so this hurts a little, but I'm just going to shut up and do it. Future repairs will gauge if this was a good idea or not, but it'll save a lot of time now which is expensive.
2) I'm planning on reconfiguring the front end a bit to allow deeper excursions into non-distorted territory, at least allow it to clean up a little bit more.
3) I'd like to design the low pass section so that it is switchable to either side of the signal path (so three position switch: LP on lower branch, LP bypassed, LP on upper branch) the problem is cost & availability of required mechanical switch. So implementing this feature would entail CMOS switching, which opens the door for additional features & CV trickery.
4) The differential stage that sits over the instability control (and is where a fair amount of the voicing comes from) will probably need to be a monolithic matched BJT pair, as short of hand matching and thermally coupling the two transistors consistency was all over the place in this section. I'll probably draw the pads to take SOIC & through hole so I can mismatch that in the event my prior analysis is full of shit.
5) If I go with CMOS switching I might get playful and build in some CV controlled feedback paths to push it deeper into the oscillating fuzz realm.
