I have a Pedulla Thunderbolt I really like but I want to tweak the tone. It has Bart BC pickups, specially wound for Pedulla, and a Bart preamp. I really like the feel of the neck and the ergonomics of the body. It just seems a bit too dark sounding. I really don't want to rout the body for new pickups (like Nordstrands). I've searched Aguilar and Glockenklang preamps and am interested. I have a bass with the Aguilar OBP-3 and Nordstrands that I like. Which of these 2 preamps (or any other) do you think will "wake up' the Barts?
