update:
there was x1 error in the previous layout.
(found out the hard way on this build attempt)
easy fix.
diagonal jumper isn't ideal, but it works so i'm happy.
now verified 🥳
confirmed 34 wide does fit well in a 1590BB/BB2, but it is tight.

yep, aionfx docs are great for those little bits of extra info.
as discussed on your zonk thread, zonk = MkI tonebender.
(mkI, mkII, mkIII are all quite different from each other, with mkI being the worst in every way)
I'm assuming you're pondering the right transistor for Q3?
the front end is essentially a MkIII tone bender.
here's some good advice on the MkIII:

note: the bias control pot will affect Q3 idle bias voltage, so i guess it's probably best to have it set in the centre when...
post up some voltage measurements at each transistor pin if you can.
would be interesting and possibly valuable to confirm what the idle bias voltages are. if the idle bias isn't quite right at certain spots, it will not operate correctly.
the zonk is basically a Mk1 tone bender.
they are an...
that's a good point, this layout has 35 rows 🥵
IIRC most vero seems to max out at either 34 or 35 rows, so im guessing it's been designed for the absolute limit.
crikey etching one of these would’ve been a heck of a task, nice one 🫡
cheers! 31x 100nF caps, x9 offboard pots; definitely a good time haha
thanks! took me ages to figure out that knob layout, pretty stoked on it though.
i’m a fan of PT2399 delays.
they’re a great definition of ‘cheap and cheerful’.
and despite the idle ‘hash noise’ they tend to have, i don’t really notice it enough for it to matter in a context where guitar amp + speaker cabinet is involved.
(in a DAW, i guess they can become undesirable)
i...
