EVH D Tuna Guitar Drop Tuner
Introducing a revolutionary new patented device called the D-Tuna! This amazing piece enables players with Floyd Rose tremolos to drop from E to D and back in an instant. Eddie Van Halen has been using this for years and now it's available to everyone for the first time. Simply replace the string locking screw from your low E saddle with the D-Tuna and included locking screws. It really works!
I had bought a Red Epiphone explorer that had a "epiphone" Licensed floyd rose with this part already on it, this is amazing it is really helpful and this will not make it go out of tune at all, but still you have to set it in a regular precise tuning. It all so helps to make your dropp D go to C and so forth.
