I've been debugging, desoldering, changing parts, and checking continuity for about a week. Tried different instruments, tried different buffers in front, different supplies and of course different ICs. Checked all pots, switch, even checked for snapped cables. Still I can't get it to work properly, so I will post here and leave it aside for a while.

some effect out of it in one or two different settings. In many cases I came near to blowing a speaker because in certain frequencies it over-reacts and gives veeeryyy loud buzzes.
Doesn't look very well-built after all the pulling and meddling I've done to make sure everything is in place.
And some voltages (sorry, tested with a 8-ish volt bat). All pots are in center pos and switch is set on 1-4 position. ( 2 to 1 and 5 to 4 )

Also here is the only schematic I found
http://elektrotanya.com/chunk_system_agent_00funk_schematic.pdf/download.htmlI think it's not the same one that was used for this layout and it is pretty difficult for someone at my level to read.
I don't think there are any placement or continuity issues as I've spend a few hours checking and rechecking it. But then again something is awfully wrong. A clue is that it is very touch-sensitive. especially when meddling with the pots.
I hope someone can get something out of all these. Sigh...
