Anybody have any experience with Bart soapbars for P-Bass? I'm specifically interested in the M45C which is their Quad Coil design. Using switches, it will set to: series/parallel/std P/reverse P. Bart and EMG both use the Reverse-P magnetic structure. This is where the bass strings are closer to the bridge, and the treble strings are closer to the neck. Fender split-P are the opposite. The Quad Coil pickup allows you to switch either way.
