It is surprising to me that there is not already some comments on this one.

We need some better photos of the top side with poti's removed to arrive at a schemo.

I have one and took it apart. It's got a JRC4558 chip in that socket. First Lovepedal that I've owned that didn't have the numbers sanded off the chip.

you wanna trace it or post more pictures of the pcb? best would be to unsolder the pots.

When I get a chance, I just got back from Vegas and am trying to catch up with my online life. The pots bend out of the way easily so de-soldering is probably not necessary.

This is pretty likely to be PaulC's Timmy if the Amp Eleven is anything to go by?

We'll have to wait and see. Wouldn't it be hilarious if this pedal ended up being really nothing at all like a Timmy?

I'm pretty sure the first half is the Timmy with the bass control and the second half is the tone control from the eternity.

can you read what's on the caps?

Nice build quality, I think.

And I like the carbon film mojo.

God I hope that's the case... I'm still hoping that he didn't do it like he told me he wouldn't.

Willful ignorance is a powerful sedative, isn´t it ?

Anybody out there who could assist me to determine where the circuit below could be derived from ? Maybe PaulC ? PaulC, are you here ?
