This is according to a schematic I have. It was a very close match to your board.
“No man is so foolish but he may sometimes give another
good counsel, and no man so wise that he may not easily err
if he takes no other counsel than his own. He that is taught
only by himself has a fool for a master.”

Ooooops !! 
Looks like an issue with the image link. I'll see if I can figure out the issue.

ALRIGHT!!
The main differences I saw were:
Your 560R was 360R on the schematic. And, there was a 2M2 pull-down resistor
on the input side of the 22n capacitor. Other that that, all matched quite well.
(The 1N4002 was a 1N4001 on the schematic). Hope this helps !!

Looks like you didn't need my help after all. Darn, a day late and a dollar short again.

hi everyone! can someone tell me is this verified schematic? what is the pots value?
i made rat clone using this topic and have some problems. effect doesn't work so good beacuse it's getting distorted very fast. i don't have so much ability to change the tone cause you can hear the tone is changing between 2 and 5 o'clock only. volume is ok. the sound at all have so much bass.
someone can help me with this?
