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?
I have been using a Marshall 2525c with my guitar for a year without any problem. Amazing amp, congrats for your product.
Last day we were on the studio I noticed something. The power switch, which shines with red light when amp is turned on, stops shining after 30 sec (does not matter if using it or not) The amp keeps on working without makeing any noise, so power switch does not go off, is just the light inside it. Valves keep on shining too of course. If I turn the power off and then on again, the red light shines again for 30 seconds and then stops. I was wondering what could this mean, or if it traduces any functioning problem I am not aware of.
Thanks in advance
