Replacing the preamp is the best thing that anyone can do with one of these basses, IMHO. I've owned one L2000 Tribute and I'm on my second L2500 Tribute. The previous owner replaced the stock preamp with an Audere 3ZB and it made all the difference!
I'm in the process of installing a switching scheme that will allow independent series/parallel/outer coil/inner coil switching for each pickup, as well as the Z-mode switch.
