76 Cliff's Gallup 4 years ago Great to hear guys. As far as the history of this, I have no idea at all, though it seems completely ideal to do and may have been practiced in certain circles. I've had bass rosin around the house for over ten years now, as I used to bow my Les Pauls and Tele ala J. Page - don't laugh ; ) - I used to be more into that atmospheric sound a cello bow can get on guitar. I knew the nature of rosin, so it just made intuitive sense to me to use it on a floater, as the job of rosin is to create friction. As far as your vibration Ratrod, don't be afraid to really get a good film on the bridge base to try to seat the bridge more solidly. Might indeed be just what you need.
