-i've changed the IC2 supply from Vb to Va so the supply of IC1 and IC2 is the same, i don't understand what kind of problem can introduce R38

who had already made pcb with previous old versions can easily replace the TLC2274 with the TL074 without change anything
I built this Dominatrix 1.2 and I though its verified, but it isn't working. I found out that Q1 and Q2 should be turned around, they are facing wrong in the layout. Am I right?
I bought new BF245As (if the old ones were broken?) and this time I tried them with a socket. I also tried replacing the TL072 and TL074 without any progress. All the wires should be working, and I checked several times the PCB for short-circuits without finding any. And yes, I did those 4 jumpers.
When having the pedal plugged in to amp the bypass works fine. Putting the effect on mutes the guitar but adds some noise. Treble pot seems to add some highs to the noise and when touching the EQ pots I can hear crackle.
Any ideas where should I look for errors? Im being desperate with this :S
