Hi all, I play a Conklin GT-5 that came with the Bartolini MK-1 pickups, and an unknown preamp (It's used on the Cort Curbow). I am thinkin' of upgrading all pickups and electronics cause I love the bass, just not too big on the sound. Any advice for pickups and a preamp. I was thinkin' EMG pickups and an Aguilar OBP-3 preamp. If anyone out there has the same bass and did any upgrade work, I'd appreciate a response. Thanks.
