I have a B.C. Rich Beast. I believe it's an NJ series, with a Floyd Rose Speedloader Tremolo.
It's been in storage for around a year or so in a padded guitar case, stood vertically in a cupboard. It's bone dry, no sign of damp (slightly dusty). It hasn't been dropped, banged or knocked, etc.
I plugged it into the app, hearing the familiar buzz you get when you touch the jack against metal, and then nothing. The guitar doesn't send any signal to the amp. I tried with an without my Zoom multi effects pedal.
My other guitars work fine, so it's definitely the Beast.
I don't know where to start in troubleshooting this problem. Could it be the pickups, the tone pots, the selector switch, the wires?
How does one go about troubleshooting a problem like this so I can narrow it down before I take it to a guitar tech?
