I have a Carvin LB20 bass that I bought new in 1992. The short story is that I casually visited the Carvin store in Santa Ana CA and they made me an offer I couldn't refuse (I think it was a custom order that had been cancelled, so they needed to get rid of it quick.) I believe it's got a maple body with a thru maple neck and ebony fingerboard. I like the instrument pretty well - it's small and light and easy to play - but I don't much care for the sound of the pickups. They seem kind of toneless, with an upper-mid clanky quality that grates on me. It's been resigned to the closet for years because of that. I think I might use it more with different pickups. I also have an idea I might give it to my nephew who is a budding musician. So, my question.... Does anyone know if Carvin pickups are standard size, that is, could I replace them with typical Fender Jazz Bass style pickups? If so, any recommendations for this instrument? I hope to hear from actual Carvin owners who have made such a switch.
