I'm new on the forum but not new to amp mods.
However my JVM 410 is doing some weird stuff.
I did a couple simple mods and the led's for the channels won't light up. The clean and crunch is awesome and you can hear the relays clicking but no lights.
And the od channels both have almost no volume.
I've changed and tested tunes so it's not that.
I cannot factory reset the head as nothing works that way at all.
Perplexing. I didn't do any mod where anything related to programming would have been damaged.
