I got a Warwick Thumb 5 a few months back and habitually let my right hand thumb rest BETWEEN the B string and the body. I guess this is bad form, but resting on top of the B string doesnt allow my hand to reach low enough to play fingerstyle comfortably. Where do you rest your left hand (if at all)? I play jazz standards in a piano trio and get called on to solo often. And the Warwick sounds pretty darn good through a SWR Super Redhead - almost enough to make me consider leaving the upright at home permanently.
