Hi, I have a bass with a passive p-bass style pickup (I believe a seymour duncan) and a disconnected EMG in the 'bridge' position. I prefer the sound of the passive pickup to emgs. I'd be looking to replace the EMG with a passive p/u of the same size. The EMG has a mounting ring and two screws like a typical guitar humbucker. Tonewise, I am not picky as I intend to mostly use the existing p-bass style 'neck' pickup. I like the tone of rics. fwiw, this is a mahogany body with a set-in maple neck. Any recommendations?
