A friend of mine has a Lakland 55-63 (I think) that is one of those Willie Weeks prototypes. Basslines dual J, passive. It's too clean and clear for him. I was trying to help him put some "snort" back into it. He also has a 55/94 and loves it. That one can get more aggressive and vintagey sounding when he wants it, and it can dial back to clean if need be. He's running decent pedals, amps, cabs, etc. but the clean of the 55-63 is too clean, too nice to be used live. But he really wants to gig it. So my question is: Put a preamp in it? Will that do it? If so, which one? Or just swap pickups? With what? Or both pickups and preamp? I have experience with Barts and Basslines stuff, but not much else. Can I get some recommendations? Please keep responses to pickups and electronics. I don't want pedal or amp recommendations. Thanks.
