Last night i went to a gig by my neighbours punk band, it was a re-union gig as they have not gigged together since they were teenagers.
Anyway their bass player used one of these vintage looking Hohner basses with a pick. Sort of a single cut Les Paul style bass, passive with flats. Man did that bass sound good. I helped the band get the sound right FOH at soundcheck and thought that bass would sound great on a reggae gig.
I think it's this one.
I know that Robbie Shakespeare used a Beatle style version but this one sounded the business.

I've no real experience with passive or semi-acoustic basses and whilst my post title is kind of tongue in cheek the tone of this bass was bang on, and it's the first time i've heard a non alembic bass that i "could" consider taking on a gig since i bought my first one in 2002. The reality is that i don't really want to add another bass to my collection so it's highly unlikely to happen. But i found the experience an interesting sonic challenge and not something I expected since most basses i hear on gigs sound fine but I don't recognise any uniqueness in tone. That tone is going to stick in my head. I know many members are not exclusively alembic users and gig or record with other basses as well. So i guess i am starting to hear why.
