Let me tell you a little bit more about my popping case:
when I cycle through all the channels on standy twice, power on, and go through all the channels quickly I don't get any pops (except when channel 3 is set to vintage).
this is the weird part.
If I switch from channel 1 to 4 or 4 to 1 quickly, I don't get a pop, but when ive been playing in channel 4 (or 3) for a while and then switch to channel 1 or 2 I get a pop.
get it?
I will try to record again later tonight and I will try cycling with power on.
