CLICK, YOU'RE IN D. CLICK, YOU'RE BACK TO E.

"You’ve just bought a very ingenious patented device that enables you to drop from E to D and back, in an instant. It really works and it’s simple to use. I’ve used it for more than 5 years, and it hasn’t failed me yet. And it won’t fail you, either. Enjoy!" -Eddie Van Halen

HERE’S WHAT YOU’VE GOT.
Your EVH D-tuna package includes:
  • an EVH D-tuna
  • an Allen wrench
  • a spring
  • two replacement long spring locking screws


HOW TO RETROFIT AND SET UP YOUR EVH D-TUNA
Your EVH D-tuna was designed to adapt to a double-locking tremolo, such as a Floyd Rose® or Floyd Rose®-licensed version fine tuner tremelo. NOTE: A low-profile, double-locking tremolo may require modification to accommodate the EVH D-tuna. You’ll be retrofitting the D-tuner on the low E-string saddle locking screw. Once it’s in place and set up, all you have to do to switch from E to D and back again is slide the mechanism in while exerting a small amount of downward pressure (for E), or out (for D).

Stablize the bridge.
NOTE:If your bridge is flush-mounted (doesn’t pull back), skip this step. However, if your bridge “floats,” it must be stabilized. You need to “block” the bridge so that it doesn’t pull back. To do this, use a shim or wedge on the block of the bridge in the tremelo cavity. Make it fit snuggly against the block so that the tremelo baseplate is level with the body and can’t pull back.

Installation
Remove the string locking screw from the low E-saddle on the bridge. Replace it with one of the two D-tuner locking screws provided, the spring assembly, and the EVH D-tuna. (If your string saddle is farther forward – closer to the pickups – use the longer of the two screws provided.) Lock the E-string in place with the D-tuner in the “out” position (this is the “D” position). IMPORTANT: Turning counterclockwise, back the fine tuner on the tremelo all the way out, so that it just touches the long screw.

Tune the E-string to D at the headstock.
Be sure to stretch new strings out fully before tuning.) Lock the string at the nut. Fine tune the E-string to D with the bridge fine tuner. Push the D-tuner in. Fine tune to E with the set screw adjuster on the D-tuner. And that’s all there is to it. Once you’ve set the EVH D-tuna up correctly, you won’t have to fine tune it again.
It’s always a good idea to check the fine-tuner adjustment on your D-tuner after you re-string, just as you would the intonation of the guitar. This may or may not be necessary, but I feel that for optimum performance, it’s a good idea to double-check. J.F.T.H.O.I...

Helpful Hints
  • I can’t emphasize this too strongly: Don’t over-tighten the fine tuner on the bridge. Keep it “backed off” as much as possible. Use the headstock tuner for any major tuning.
  • To help stabilize new strings, stretch them by physically pulling on them one by one.
  • When sliding the EVH D-tuna back and forth, push the unit down (towards the body) to take the tension off.
