Hi,
I have build the 3verb pedal, but it does not function well when i turn the decay knob further than 12 o clock. After playing a bit it gives a high oscillation sound that keeps ringing until i turn down the decay knob. Does any of you have experienced this before? I have found several threads that describe a similar problem, but my german is not great. Would you be able to help me identify the problem?
I have installed a 25k trim pot, as I found this could possibly solve the problem. However, I experience the same problem.
I will try to upload some photo’s/ sounds tomorrow.
Thanks,
Koen
