Hi, I have a G&L L-2500 tribby that is having some issues. I replaced the battery a couple days ago and since, the only way to get any volume for it is to have the bass, treble, and volume turned all the way up. I have tried different batteries and have the same issue with the batteries being brand new and full of energy. I have never had a problem with this bass until now and I need her back!! Any ideas?
