Allparts Introduces The Tremol-No: The Tremol-No is the new user-friendly device that can be added to most tremolo equipped guitars, giving the player the ability to turn their tremolo system 'on' or 'off' in seconds. There is no drilling, no routing, and no permanent modifications to the guitar. Players can now switch between Hardtail, Dive-Only, or Full Floating modes on their favorite guitar, all within seconds of each other.
