I've noticed that when switching channels, specifically from any other channel to the Clean channel in Green mode, I get an audible pop. Not like a firecracker going off, but definitely bothersome. If I set the Clean channel to Orange mode the pop does not happen. So, the pop only happens when switching to Clean/Green. This pop occurs when switching via the front panel buttons or my midi Voodoo Lab ground Control.
I've had another JVM410H owner try to reproduce the issue, and they experienced the same pop when switching via the front panel buttons, but did not experience the pop when using the Marshall footswitch.
How can I correct this?
