SOURCE: What's your problem?I have two Fishman amps.The older Loudbox 100 single channel and a Loudbox mini. I am trying to find the service manual for the older fishman as I have a fault with it and the

Fishman iis you best bet http://www.fishman.com

You 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.

How do I get a schematic diagram for Fishman SA220?


Fishman generally doesn't supply schematics to end users. Your best bet would be to find the authorized repair center nearest to you and jus t let them deal with it.

Fishman Loudbox amplifier rattle sound on bass notes


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.

Low volume from Fishman Loudbox Mini mic input, using brand new XLR cable and dynamic mic. Mic works just fine on instrument input using a Hi-Z cable so problem is not mik


I have seen defective XLR cables so check it with an ohmmeter. It is possible the mic input preamp has been damaged. If that is the case, the unit will have to be repaired.

I bought a second hand Fishman LoudBox Performer. The problem is that the Aux-in for the headphone doesn't work. So sick... What can I do? tnx


I don't understand your question. The "Aux in" is just that an input that goes to the power amp. Please note that the Fishman Loudbox does NOT have a headphone jack so don't be disappointed as there plain isn't a headphone jack on this unit. I would recommend that you get a small headphone amplifier for the purpose... or even go to a thrift store and get an old stereo system that has a headphone jack and use that.

My Fishman Loudbox 100 bass speaker buzzes- what could it be? Someone suggests it could be a poor ground, and to replace the input wire, etc. Does he mean the guitar input cable? The speaker does not sound...


It is a poor ground but it is not necessarily in your amp.
If it is only buzzing when you have a guitar or other piece of equipment connected try a new lead cable.
If it buzzes all of the time......remove the cover at the rear of the amp and remove control panel.
Inspect the feed line to the input. If it is loose or broken....repair or take to have repaired.
