The group leader is fine with anything that sounds a bit more acoustic than my Alembics which I agree didn't go that well with the group sound.
The question above is really coming from me. I borrowed a Rob Allen last week, took it to a practice and they loved the sound and how well it blended in. It certainly wasn't the sound of an upright but played with the strings with which it was strung it nicely melded with the rest of the group (who not only do what I'd refer to as electrified bluegrass, similar to T by T, Grisman, etc., but want to play at least one set of acoustic tunes dominated by old time blues players (e.g., Blind Lemon Jefferson, Rev. Gary Davis, Light'n Hopkins, etc.). The RA I borrowed was a model with an ebony fretboard and no markings. I'm currently looking at possibly purchasing a fretless RA (out of town that I wont be able to play before purchasing) that has a rosewood fretboard and fretmarkers and was just wondering if this is going to result in a tone that is significantly different and/or if the tone of a Turner would be a significantly different.
