I could start a thread "What recent unexpected bass knocked your socks off" on Basses BG... but I'd rather talk about it here. The recent unexpected bass for me would be these late '60s Dano made basses. (Coral Deluxe Bass & Silvertone Hornet) I just love them in so many ways, but most especially the way they sound. I love a good P-bass, love a good J, love a T-bird, love a Darkstar'd bass. Love them all really - I don't rate things like that. Different flavors that all provoke/inspire different playing. Never owned or played a Dano until I got the Coral. And now the Hornet - its cousin really, definitely related. The neck is probably next - wide P nut, narrow heal, 22 frets. Kinda a straight rail compared to the tapered Fender-style. I own 20, 21, 22 and 24 fret basses - but my fave is 22. The profile is a flat D - really comfy/fast. The rest gets into style and design and curious engineering - the quirky-cool part of a Dano. Some real innovations, some odd but functional particulars.
Hard to say if it's only some players who would gravitate to these basses. I was in my SF used guitar shop today and was talking to one of the owners about the Dano/Silvertone Hornet. He said he knows a guy who runs/owns a recording studio and they have one there if anyone wants to record with it. Sez' it blows away Fender P-basses all day long. It is like that - if you have ears you'll hear it. Playing through a vintage B15N not only accentuates how awesome it sounds, it seems to have been made for that sort of bass. Like a modern 18v 6-string bass through a Warwick or similarly high-end rig - it's the coupling of the two that fully expresses the resulting gestalt. Wouldn't want to play Jazz Fusion with the Coral or Hornet - but if push came to shove, I'd throw it down through it's unique character and I bet it would sound awesome!
Here's a recent recording my band made - this song I'm playing the Coral thru my '76 B15N w/late '60s JBL D140R - delivers the tone I hear in my head. (my tone)
