I have one of these basses, and it has become an electronic nightmare. Popping noises, hum , crackleing,....
I took it to a luthier to have the pots replaced,...here is what he said.
I finally got some time to look at your bass agian. When I took a closer look inside the control plate I realized that all 3 pots are sodered directly onto the circuit board and cannot be removed. There are at least 3 soder connections for each pot and one has 6 contacts- trying to remove these from the circuit board is very difficult if not impossible (I cannot unsoder 3 or 6 contact points at the same time and there in lies the problem- further too much heat could damage the components on the circuit board.. Further, any replacement pots would have to be an exact duplicate pot to line up with the circuit board contact points....in other words Fender pots which I do not have access to. Further these pots are smaller (mini pots) and the stacked one is unique to Fender. In order to replace the pots you would have to order the complete circuit board from Fender. I wrote down the part # for you off the circuit board.
While I had it apart I lubricated all three pots with a quality lubricant and spent some time turning the pots to work in the lubricant. They seem to be working much better but one pot does not seem to make much change in tone when turned clockwise and counter clockwise. At any rate there isn't much more I can do with it....it is what it is. Call me at xxx-xxxx to arrange a time to drop by and pick it up. There is no charge for the work done; just wish I could have better news for you
Do any of you folks have any comments,..or solutions ?
