Last night I went to a jam and played my first Rickenbacker. It was a 70's original, and it was the actual bass used on Chaka Khan's "Tell me Something Good!" The amp was an old Carvin head with a 2x15 speaker. The really cool thing about playing this bass fingerstyle was how, by plucking the strings just slightly harder, you could get a hint of buzz that makes the note stand out. Even on really low notes. Playing slap was a little bit of a challenge, had a hard time coaxing a convincing "thump". But popping the strings was great - very cool vintage woody sound, exactly like those old Sly Stone tunes. My normal bass is a Pedulla Rapture, which sounds like a P-bass with really bright highs.
