I have a dean bass that has what I believe to be a dead pickup and I'm just gutting the electronics to replace them. I normally work with guitars so bass guitar pickups are a little new to me. The issue I'm having is that it's a 4 string bass with a 4 inch soapbar pickup but all of the soapbox pickups that I see that match this description are for 5 or 6 string bass. Does anyone have any budget recommendations?
