As some of you may know, I recently aquired a '92 Streamer with a dead P pickup and a crapped-out preamp. I threw a Basslines Quarter Pounder in there with the other Basslines J and will be installing the Aguilar OBP-3. My question is, should I have a pro (im not going to be responsible for screwing up a bass) drill a hole in the body for a switch for the selectable mids, or should I just save the trouble and go with a push/pull pot? I really like switches (who doesn't?). By the way, I will have pictures soon. I know I said that last time, but things got crazy. Also, should I wait for any after-holidays sales before buying the preamp? Thanks.
