I know we don't have the biggest bass population here but here we go:
I have a BC Rich Eagle (REB-2) that is a 2 P Bass Pickup setup. I currently have a QP (SPB-3) in the neck and a tone Emporium Vintage in the bridge (what I had lying around when I pulled the EMG's). The vintage pickup is just way too weak to combine well with the Quarter Pounder, so I am looking for something to better match when both on. Control setup is V (Neck) - Switch - V (Bridge) - Master Tone.
Of course the obvious answer is another SPB-3, but throwing a feeler out there. I play lots of stuff on it but it will be mainly for 80's metal type sounds. Think Duff / Rachel Bolan type tones.
