I've got a G&L L2500 Tribute that I really like. I really like this bass, but I don't like the preamp and I'm missing the mid controls I had on my former bass. I've been debating about a pre and have been comparing Bartolini, Aguilar, and Audere. I've read that the Audere works really well with soapbar pups and Jazz pups, but how would they sound with the MFD humbuckers in my L2500 Tribute? I was thinking about going the 3ZB route with vol, bal, bass/treb stack, high mid/low mid stack. I've replaced the parallel/series switch in my L2500 Tribute with an outer coils/parallel/inner coils switch. Thanks!
