Guys I'm not technical or handy at all. I see the Geezer P/J replacement pickups and they have the solderless connections. I want to buy them. My bass has an active preamp but no active/passive switch which is a must for me in case a battery goes out live. Is there a preamp I can buy that will work with the Geezer PJ solderless set which will include a passive/active switch and drop into my bass? A picture of my bass is included.
