Thanks !EDIT does it have tails (ie buffered bypass)?
EDIT 2 does this happen in the minimal configuration (guitar > pedal > amp?)
Very important to check, as sometimes the popping pedal is NOT the one with the DC offset problem.
-the ed2 is true bypass only
-it happens all the time, in any configuration... first loud pop (if I’M right this comes from the fact that the pedal needs more current when engaged for the first time ?), and then quieter pops when using it.
Does that help figuring it out ?
