Look on this

P.S. you need adding 18 power converter with Max1044(ICL7660S)

Drew up a layout of this one if anyone wants a go.

Drew up a new schematic based on the layout. The original schema appears to disappeared. Hopefully this is accurate if you would all mind to check.

The schematic pic in OP's post was hotlinked from a thread on guitar-fx-layouts:
http://guitar-fx-layouts.42897.x6.nabbl ... 18170.html
which was a reposting of the schematic originally posted on this site in this thread.

Looks a bit like the ROG Azabache, without the interstage clipper pairs.

I have updated my schematic drawing to match. I have also attached a layout (unverified) I just put together. Comments are welcome.

Not quite, the azabache uses a BMP tone control, this a baxandall also. So it's different as far as these jfet preamps can be different, which is not much. Maybe there's some other ROG that's more similar.

I have built one and it sounds enough good, but I have serious doubts that is JHS Twin Twelve. Anyone has some gutshots?

Hi there, here it is with lid off. Hope it helps.
I can zoom into some of components if it helps, but am not super comfortable dissembling it completely.

Very interesting, kaludjerko! I will look carefully later, but, as i saw, there are no values on the caps

After I looked at the photo from kaludjerko it's clear that the schematic above has nothing to do with JHS Twin Twelve (for example, in the photo are 3 resistors of 560 ohms and in the schematic is none).
