This drop D guitar tuner is a revolutionary new patented device that lets you to drop from E to D and back, in an instant. EVH has already been using it on his guitars for five years. It's simple to use and it 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.
The EVH D-Tuna 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!
Each D-Tuna kit contains:
- 1 EVH D-Tuna Unit
- 2 String lock screws
- 1 Spring
- 1 Fine tuning Allen wrench
Q:How easy is it to install the EVH D-Tuna?
A: If you follow all of the directions step by step, it will be a very smooth install.
Q: Why do the other strings go out of tune when I drop to D?
A:The bridge must be stabilized first. This is done by blocking the bridge so it can not pull up. You can also use a tremolo stabilizer such as the WD or the Hipshot Tremsetter.
Q: Can the D-tuna be used on any Floyd Rose Tremolo?
A: It can be used on any Floyd Rose or Licensed Floyd Rose Tremolo with the long locking screw, where the fine tuner on the bridge presses directly on the locking screw.
Q: Why can't I get a full step drop?
A: There are few things to check. First, tune the "D" string. Then fine tune the "E" (using the D-tuna fine tuner). Back the fine tuner on the bridge off, then retune the "D" at the headstock. Did you use the right length locking screw? If the head sticks out of the D-tuna completely, it is too long.
Q: Can the D-tuna be used if the guitar is tuned down a 1/2 step?
A: Yes - Set if for D Flat in the "out" position and E Flat in the "in" position.
Q: What gauge strings are best?
A: Any! The D-Tuna works with all standard electric sets. (.009 thru .012)
Q: Can I use the D-Tuna on any other strings?
A: It will change the pitch of any string but it is designed for the low "E" string only.
Q: Can I use it on a low profile tremolo?
A: Yes, but it depends on how deep the bridge is set. A very deep cavity may require some minor routing, although most will not. Don't forget to stabilize the bridge first!
Q: Do I have to remove the D-tuna during string changes?
A: No , it will stay on the locking screw at all times.
