My Squier Jazz Bass has been in the shop for a couple of months with some kind of issue with the electronics. This is the second time I had to take it to the shop where it gets fixed at. For some reason, there is no sound coming out of it. All the knobs would be maxed out, but no sound. The tech I took it to tested the pots and input jack and said they were working fine. So he said there could be something else that could be causing the problem. Would anyone know what could be wrong with my bass since the pots and jack are perfectly fine? This is my first bass and my grandmother bought it, so I would hate to sell it on CL as an "as-is" or project bass.
