OK, so I have this 2009 Michael Kelly Dragonfly fretless 5-string that I've recently just started playing amplified in front of audiences. Most of the time, this works nicely and the sound is lovely, warm and woody, just like the unamplified sound. So far so good. From time to time, the electronics cut out entirely, drop in volume or ramp up in volume and start feeding back, it's fairly unpredictable. So far, I've tried: several new batteries in the pre-amp several new patch cables several mixing boards several amps several rooms trying to isolate the problem, which appears to be something in the guitar electronics - this set of problems persists across changes in all the other factors listed above. Electrified instruments are a newish thing in my stable of instruments, so I'm sure how to go about diagnosing these electronic gremlins. Or if it's even worth the effort if the factory Fishman electronics are just cheap, throwaway components to begin with, which some forum postings seem to suggest is the case. Any suggestions, I'm all ears - dh.
