I've finally decided against buying a new bass in favor of upgrading my current one (a Guild Pilot Deluxe 5). After looking over a bunch of preamps and pickups I've decided to drop an Aguilar OBP-3 and 2 EMG 40P5s in the bass. Is anyone aware of any problems or conflictions that may occur with this setup? I looked around the forums and couldn't find anything too specific. Thanks!
