20 Most Recent Fishman Loudbox 100 Acoustic Guitar Amplifier Questions & Answers

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 iis you best bet http://www.fishman.comYou can download the user manuals, they do have a block diagram, but the scan is pretty bad. It may end up the person looking at it is going to need to rely upon their general knowledge.My own suggestion is to pull the chassis out so you can work on it while powering it. And then work your way through the amp with either a signal source plugged in at the input, and with high impedance headphones with test lead ends, go through each audio stage carefully. until the fault is isolated. If it is not caps or the rectifiers in the power supply, faulty ground connections to chassis or faceplate, a faulty 4558 is most probable. The headphone approach is the fastest way to address this last one. If a different series of preamp chip is used, a good source for the IC datasheets in general is Digikey http://www.digikey.com and parts too.

Hope this helps!

Unplug all cables, turn all gains and volume to zero and switch on. If the fuse still blows I'm afraid it has a power supply fault and will need repairing by a tech.

Also, make sure it is a T-type or slow blow fuse of the correct rating. Ensure that if a mains voltage selector exists that it is set for your local mains voltage.

Is it stuck in tuner mode perhaps.

This is an indication of an internal component failure. The unit needs to be sent in for service. It requires special tools and skill to service.

We will need the model of the Fishman you're using to advise you.

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.

You may have the tuner too far away from the guitar or the batteries may be going flat. Check to make sure that there is nothing blocking the microphone hole and that there is no other noises in the area which could be affecting what the tuner is hearing

can you tell if there is a wire broken? if you know how to use a vom meter you can check to see if you have continuity if you don't then you have a wire problem & make sure that your battery is good.
