Even with G&L's standard crappy shielding job, my new LB-100 is pretty much dead quiet. I have thought about the MFD switch. The stock LB-100 pickup that I have, on my LB with La Bella DTFs and an Empress body, sounds lovely, warm and woody: a characteristic sound that I associate with the Lindy Fralin pickups I have elsewhere. My Tribby SB-2's MFD split pickup sounds quite different, with more bite and character to it—especially when dimed. It says "G&L" when I hear it. BTW, as an experiment, I bought an SB MFD pickup and put it into an old Yamaha BB300 that I had on the rack, and that pickup character is still there (absent the rest of the SB bass's feature set). That thing's a great-sounding tank of a P-bass now.
