If anyone can help.. i have a gibson L4a i bought used and i absolutely love the cuitar its like a gibson j-200.. the electronics all work but the volume goes from off to full blast with a little turn. meaning no matter how much you turn the knob it doesnt efffect volume. its always full blast. until ots off. so no volume control:-( this is troublesome as sometimes soundguys will ask you to turn down and I cant :-( anyone have any idea how to fix this o r why its doing this? its a fishman plus.. im going to try to take it to get fixed but i pray i wont need a new one will cost 500$!!(fishman plus module) any ideas? can this be fixed?

From the sound of things, it may just be the potentiometer that is bad.
Depending on how it is wired, it also could be a capacitor or diode.
Either way, your only looking about $10 in parts.

Jun 21, 2008 02:05 pm Yep, if everything else on it is working proper you should not be looking at a huge bill. I had one worked on years ago and it was an issue as Rob mentioned, just s simple fix that took him about 10 minutes to fix and I was out the door. He knew exactly what the issue was so that helped.
Jun 21, 2008 07:23 pm thank you!! this is very encouraging!... also what is this notch knob? i cant tell it is doing anything when i turn it>?

Jun 21, 2008 08:15 pm If I am not mistaken the notch knob should be a filter of sorts. It helps notch out the frequency that can often cause feedback. It is only good for a very small EQ type sweep up to maybe 300Hz or so. Many acoustic's have an issue in that area and below when using transducer's and that can help eliminate feedback when running through a big PA system.
