I'm toying with an idea to modify a 5 string with 2 pickups in the Rickenbacker positions. I've seen Ric5's modification of standard Ric pickups to span 5 strings but am looking at 5 string pickups that have similar characteristics of the older single coils. I'm listening to a lot of Mike Mills lately. Jason Lollar makes a '51 P with the same resistance as Rics in a 5 string version. What else do I need to consider? It doesn't need to look anything like an original. For those who are going to ask "Why?" Because I want to and enjoy this kind of thing.
