Hi - I recently picked up a Westone fretless recently and I've began to notice (who now?) a buzz when my hands are free of the bass. I've swapped cables and basses and the noise is definately from this bass. If I touch the strings or the metal outer to the jack then the noise dulls. I can supress it through my GX-700 effects but that's not the point. Any help please on where I need to get my soldering iron too? Regards - Dave.
