I like the Shubb(spelling?). I have one of the "gliders." I bought it direct form the manufacturer at a NAMM show. It took me about month to decide I hated it (BTW, don't park it behind the nut; park it right on the nut and it won't effect your tuning). I've had several Kysers and they seem to loose their tension after a while. They sure are convenient, though.
