I wasn't happy with the Bigsby so thought I'd try a few things. Stringing over the tension bar worked okay but there wasn't much clearance between the bar and the strings so I removed the bar completely. Also put a couple of nylon washers between the body and the rear of the Bigsby to better match the body curve and tightened the mounting screws in a way that the arm moves freely with no friction without strings. If all four are very tight the arm gets very stiff. Two tight and two firm did the trick. I've got a roller bridge on the way but really don't need it.
