Any effects gurus, if you could help me figure out this problem, it would be much appreciated:
I just redid my pedalboard to have about 18 pedal effects. Most are true bypass, a few are buffered, I'm happy with the sound and I'm not noticing too much high end loss or extra hum. But there is one problem I'm having and I have NO idea how to debug it. Basically, when I start playing, everything is fine, but after an hour or so, when I have an overdrive pedal on, I start to get this really weird crackly clipping noise at the end of a played note or chord. I turn off all my pedals and turn them back on, and the same problem happens. If I give them a bit of time, the problem goes away. This only happens when overdrive pedals are on, but it happens with all of them. It doesn't seem to be the amp, because if I then unplug from the effects and plug straight into the amp and crank it, there aren't any problems. It could be something weird going on with my power supply, but I really am not sure and don't know how to tell. Any ideas?
