Hey, I snagged an RB999 'project' bass off eBay. I may need to replace the electronics; I'm not sure what 3rd-party preamps are compatible with the Ibanez low-impedance pickups. (Debating the Aguilar vs. the AGC). Any thoughts? I'm converting it to a fretless, so anything that can give me a nice Mick Karn-esque, Wal Mark I vibe would be lovely, although I realize you cannot totally transform the sonic character of a very small lightweight bass! cheers --!
