The EVH D-Tuna is a revolutionary device that lets you to drop from E to D and back, in an instant!. It is made from the highest quality hardened steel. The patented design allows for precise fine-tuning adjustment, is simple to set up, easy to use and really works! The EVH D-tuna was designed to adapt to a double-locking tremolo, such as a Floyd Rose® or Floyd Rose®-licensed version fine tuner tremolo.
Note: - A low-profile, double-locking tremolo may require modification to accommodate the EVH D-tuna. - If your bridge 'floats', it must be stabilized. You need to 'block' the bridge using a shim or wedge, or lock with a tremol-no unit so that it doesn't pull back.
