I have a Fishman Prefix Plus-T in a Carvin Cobalt Guitar. To replace the battery do I have to remove/loosen the two screws holding the sides of the battery cover or is the battery supposed to slide down without removing the screws???

The little plastic catch above the word "prefix" should release the battery carrier.

Either the speakers have loosened from the faceplate, or one or more have blown. Open the amp and tighten them down. If that doesn't fix it, remove them a take them to the nearest speaker repair shop for a checkup. If blown either have them re-coned or replace them.

Fishman Prefix Plus preamp on my acoustic guitar picks up the unwound strings well but the wound strings are barely audible

You could try boosting the bass and reducing the highs on the EQ setting, however there MAY be a probllem with the pickup, not the preamp.

My Fishman Prefix plus is not working through an amplifier and the tuner will not stay lit

Check the battery in the preamp. Also adjust the eq to see if you might be clipping the frequency you are generating.

ALSO do not overdrive a tuner... they get confused and won't register.

Unit inoperative, one LED blip on battery install only.

Its possible that if you changed strings the saddle might have changed position in its slot. It has to sit uniformly on top of the piezo element in order to work properly. Try testing the pickup(piezo element) first before suspecting the preamp.
