    Hey all, i just received my new seymour duncan quarter pounders to replace the standard pickups in my 2004 MIA p bass with S -1 switch. I have removed the pick guard and uh oh.....wires every where!! The new pickups are wired standard and appear different configuration of original ones in the bass. Has anyone had experience with this or is there a video somewhere i can watch for this particular scenario? Please help!!

    Nothing should be different , you should be able to simply swap pups , matching the black & white wires.

    Wire the pickups to the pots as recommended by the manufacturer. Ignore the switch.

    Yeah na, not that simple. Yes i can see how easy it is on a standard p bass but the configuration is completely different with S-1 switch. I have now managed to get the pickups installed however when i engage the s1 switch it completely cuts the sound. Not concerned as i never use it anyway. Thanks for your replys

    Does the S1 switch do series/parallel for the split pickup? If so, then you would need to cut the short wire between the two coils, graft on some longer wire, and solder those new ends to their respective spots on the S1 switch.

    If it were me, I'd completely remove the S1 and throw a regular ol' CTS 500k in there.
