They intrigue me and the tone really us pretty nice, but the seemingly inescapable fret buzz just irks me. It's not something like an electric in which if you just play it loud enough you won't hear buzzing anymore. Also no place to rest my thumb, but that can be worked around with different techniques I guess.
Been trying to keep myself from buying one on impulse too. I already have two bass guitars, but told myself I'd play more if I had an acoustic one too, which is, of course, total bullshit. This sounds great, though! Wonderful rendition of Orion.
I say sell one and get it. Since THREE basses is definitely overkill. And I trust you will actually play it more since normally I can't be assed with amps and such and this is easier. And you CAN still plug it in if you wanted, if you get one with a pickup/microphone.
