My L2500 is wired inner coils I dig it.I have my single coil mode set to the outer coils, which works well as a P sound for the neck pickup or a decent J imitation with both pickups selected.
I had it set to inner for a while - a different sound for sure. Not much different for the neck soloed, but a really different sound with both pickups on.
Luckily I have two very good luthiers nearby and, between the two of them, they've done everything for me from pro setups to assembling a frankenbass from parts I bought. I'd have no reservations about having either of them do a wiring change.
