1 : Are the batteries OK?
2 : Are the connectors in the batter boxes OK? (Chck for corrosion).
3 : Is the power getting to the circuit? (Maybe the wire is off
the back of the battery box).
4 : Is the jack socket OK?
5 : Are the wires to the jack socket OK? (Twisted, loose or broken
off?).
6 : Does anything look 'odd' on the circuit? (Moisture, corrosion,
loose wires, damage).
7 : Are the pots OK?
8 : I assume the jack lead and amplifier are working..... !?
