Hello everybody.

I'm the happy owner of a 50W Overtone since 2008.

Everything was running well until last concert: the mid boost of this wonderful amp did not work anymore.

More precisely: when I'm switching on the pedal switch (the green one), the mid boost don't goes on.
But when I'm switching it on the rear switch (manual vs pedal) it works.

In another way, I can't switch it on or off anymore with my pedal controller

Does anybody have an explanation?

Thanks a lot
Cisco
