You've been busy! Great builds. I'm glad you are getting some mileage out of my audio router board.

I've had a look in all the obvious places but can't find a schem or a layout, do you remember where you got it from?
I suppose a good place to start is a Supreaux and a charge pump

Here is a link to the layout I used:

http://guitar-fx-layouts.42897.x6.nabble.com/Silvertone-1485-Twin-Twelve-td18170.html

I have another question about the Silvertone/Twin Twelve pedal
I got the layout you used, and I found also this one: http://tagboardeffects.blogspot.it/search?q=twin+twelve
and this one: http://effectslayouts.blogspot.it/2017/07/jhs-twin-twelve-v1.html

Except a bit difference in the charge pump and a missing probably pulldown resistor (10M, is it too high? ???) the layouts are pretty much the same and of course them come from the same source.
Here the two veroboard layouts and the basic schematic.







There's some doubt about the accuracy and the fidelity of the schematic about the JHS Twin Twelve.
Did you have find problem of noise or something else with this circuit?
And how it sounds comparing it with the original JHS, at least listening the demo?

Thanks! ;)
