So I got my hands on this little puppy.
BTDR-3 brick based reverb. Trying to trace it - would love some help, I know some of us are photoshop wizards and can make overlapping traces very easy to find.
Here we go:

Now with the brick dessoldered:

And component values:

Can you help me out with this?

Cheers!!

Please, make also a shot from the other PCB-Side.
I personally put the PCB on the scanner and get the image in this way using an high resolution.

There are 2 photos from the back side, with and without the brick.
Need another photo? Any specific angle?

Only a photo from the complete solder side without backlight.

(sorry, I already resoldered the brick. This pedals not mine, so I had to put it together asap)

Here are two more, front and back without backlight.

Thanks, but the conductors under the potentiometers are not visible.
Could you sketch in it on the image?

I've desoldered de dual-gang pot so I could take pics. Here:

Thanks for the images.
I going to make an approximated PCB copy for tracing the circuit, but it will takes time.
Please tell me the board sizes.

Its 113mmx67mm. just measured.

Too many missing tracks.
For this reason, it is not possible to trace the circuit.
