All good info here. Thanks. There's more professional EB0 players than I imagined.
I have an old '68 EB0 that I break out once in a while on small nightclub gigs when we're playing '60's tunes, but it's hard to justify doing it, tonally, because all my more modern basses sound so much better. But that neck. What a great feeling neck! Most comfortable bass I've ever played.
Also, I've found that if I run the EB0 through an old Cry Baby Wah pedal I can adjust the tone for room acoustics much better than if I omit it altogether, and can add a bit of treble instantly for solos.
