Thanks guys, especially Puretube!!

I've finally solved the problem of LFO ticking in my washburn chorus.
It's pretty beat up but it has a very nice analog chorus sound. Very unlike a BOSS CE-2, more flanger like actually. But without all the shared knowledge here I could never have made it. Now, thanks to guys like Mark Hammer and Puretube,  I know what heterodyning, stray capacitance and careful grounding means in LFO/BBD based effects.

It was broken and repairs included resoldering wires to/from the pcb and fixing the broken pcb. After having done that I noticed ticking from the LFO. Then I started reading all threads on LFO/BBD based designs, thinking a lot, trying a few things but to no avail. Today I saw puretubes tips:

Another cause for "ticking": long free-running wires from the Schmitt-trigger`s output to "speed/rate"-pots or LEDs are x-mitting antennas
for the sharp spikes that will induce into the audio-path when criss-crossed
through the box.

I moved the wires going to the speed pot and yet again resoldered a fishy groundpoint and BINGO
This is a great place to be! And don't forget it when flame wars are raging :wink:
Best!
