I would like to hear more examples of the VI (and/ or related instruments) on the more bassy side of things, to see how far it can go in that direction.
IMHO, the amplifier that you choose to play a bass VI through greatly determines the sonic direction... When I was shopping for amps for mine, I found that plugging it into modern bass amps resulted in a tone not unlike what you'd expect from a normal 4-stringer, obviously related to pickup settings chosen as certain settings emphasize/de-emphasize the bottom as well... As that is not the sound I was going for (I use it more as a deep guitar), I moved along to guitar amps and found the sound I associate a bass VI with. Obviously the bottom isn't nearly as full as what you get out of a bass amp (especially since you want to cut the bottom out so as to avoid blowing your speakers...), but in a pinch you can still get a bass sound. I ultimately settled on a Fender 59' Bassman RI as my primary amp for my VI... The only amp that I liked better is a Fender Twin, but I got a great deal on a second-hand Bassman.
dont they sound and play like a guitar??
See above... Dependent on pickup settings and choice of notes/chords...playing chords on the upper strings in "normal" guitar range results in a distinctly guitar sound... Playing chords in baritone range (using the low A string) results in a deep guitar/baritone sound... Fingerstylin' the bottom 4 strings results in a bass sound... Playing in the upper register results in the sound that I generally associate with a VI...even though its well within guitar-range, its that distinct "deep moody" guitar sound like what Robert Smith plays in.
The feel is very much like a guitar with bass strings on it, maybe not something that is immediately easy to play, but definitely easier to play chords on than a 32" or 34" bass... The spacing is very guitar-like...and if your hands are already strong from playing heavy strings the transition isn't so bad. From what others have said, and I agree...that most people that play a VI as their primary instrument develop their own style to accommodate for the instrument's eccentricities...
