The EVH D-Tuna is an amazing patented invention that allows players to drop the low E string to D and back, in an instant with out having to undo the locking nut of the Floyd Rose. Eddie Van Halen has been using the D-Tuna on personal guitars as well as signature series locking tremolo-equipped guitars since the early 90's. It is part of his standard gear on any guitar with a Floyd Rose. D-Tuna's have been become a must have for any player that switches back and forth from E to D. Thousands have been sold all over the world. Who else uses D-Tuna's? Well EVH D-Tuna's are used and endorsed by players like Warren DeMartini (RATT), Michael Wilton (Queensryche) and Dave "The Snake" Sabo (Skid Row) just to name a few. Why? Because it is simple to use and it just works.
Here is what Eddie Van Halen has to say about the EVH D-Tuna:
"It couldn't be easier to install. You remove the string locking screw from the low E-saddle on the bridge and replace it with one of the two D-Tuna locking screws, the spring assembly and the D-Tuna. And that's just about all there is to it." - Edward Van Halen
