[quote name='FlatEric' post='728631' date='Jan 29 2010, 02:03 PM']Two things to bear in mind, I LOVE these basses and . . . . . . . I'm elctronically blind!!!
So, from experience only - some electrical issues can be down to the phase switch.
You didn't say if it was like this or it has become like it.
I would do a bit of simple elimination. A new phase switch is not to many £$£$ and easy to fit.
The phase switch is also a coil selector, on the back PUP only, so may have something to do with it. I will forward this on to someone who may have the answer.[/quote]
The bass arrived to home from USA with a non-original three possition black switch in the phase position and the same problem I have now.
My first try was to replace the phase switch for a DPDT on-on switch just like the originals ones.
It did not solve the problem. Anyway to replace that switch was a must.
As I said before I am goin to try with the pot. Your explication about the way double-single coil system works (grounding coil, the pot and so), makes me think the tone pot is not working properly and as a result is not grounding the coil.
Many thanks FlaEric.
