Are there construction differences between violin and fiddle?
Yes - Nobody cares if you jump on a fiddle. Seriously though, no difference in construction that I know of. It's all down to how you play it. Itzhak Perlman calls his Stradivarius a fiddle.
As for the bass thing: I don't want bassists to sound like bassists!
You're in luck then - they frequently don't these days. 😀 They are mostly frustrated "lead" guitarists.
The mark of a really good player for me is someone who can do something really interesting while still holding down the traditional role of the bass, underpinning the music. Tony Levin, Jaco Pastorius, John Entwhistle and Billy Sheehan spring to mind. Don't give me someone who goes wheedely-wheedely-whee
in the upper registers of a six string all the time. Same with drummers - if they can't do it with a single pedal, kick, snare and hats, they can't do it.
