Question about Crate FlexWave FW15 Guitar Amp Combo, 15 Watt Single 8 Speaker
The sound circuit on your system is like this:
1 = on guitar : pickup - signal potentiometer - signal tone potentiometer - plug. Simple test : plug the guitar in another amplifier to test it.
2 = on your amplifier : plug - preamplifier - volume control - reverb system - final amplifier. Since you get a good volume otherwise then the problem is before the final amplifier. Start by checking the cable with an ohmmeter for breaks and replace it if necessary.To test the rest you must dismantle it and access the components: start by shorting the potentiometer (center plot/signal input to the signal output) - the volume should go to the max. Then check that the preamp is working by touching the input wire - the brum should be clearly audible. Finally check the power source, the voltage on one of its power rails might be down and the preamp might not be powered.
