This was more about me getting the hang of Express PCB's schematic software than an earth shaking revelation. There may be drawing errors but the values are correct.

Still, thanks for letting us be a part of the experience, whatever its nature
I was just wondering what PaulC would call this

That switchable 4k7 cannot go directly from pin2 to ground (through the switch allright). There must be a cap in between for DC decoupling.
Otherwise I do not see any resemblance to any known circuit on the market

Nope.
That's how killed they are. They were there but during months of painstakingly tuning te sound they were found not to be required for the ultimate tone.

You're right, my mistake.
It heads to a 0.1uf and the input cap should be a .047uf, I'll correct it soon.
