Product Description

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

FAQ's

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.

This thing is Awesome!

Product Review

Product description nailed it. Easy to install and just an awesome thing to have. Drop to D and back to E with little effort and no issues or set up complications. I would absolutely recommend this product. NOTE: my Floyd is recessed and the extension on the D TUNA does effect how far I can pull up on the bar. Not the D TUNAS fault, just something to be aware of.

Works Perfect every time!

Product Review

Once you get this thing installed, all you have to do is pull it out to drop to D. Then just push it in to go back to E. It’s just that simple!

Well worth the money !

Product Review

Works exactly as it is supposed to. A must have for Floyd trems. However, some useful information before you purchase, you MUST block your trem for down motion only. You can not go full float. So if you do a lot of pulling up on your trem do not purchase !

Works pretty good if you have trem stabilized.

Product Review

It's a bit sloppy when disengaged. could have slightly better tolerance.

genius

Product Review

Note: This will only work on a Floyd Rose style bridge. It is also worth noting that this will not work well at all on a floating Trem. The D-Tuna makes it impossible to do pull back harmonic screams as the units length will rest beyond the cut out in the wood, and on floating trems your guitar will go out of tune. Only install this on Non floating Floyd's.

I love this feature

Product Review

Is it possible to install the drop D tuna on a hard tail? I would love to have this feature as part of my fender EVH USA Custome Deluxe HT guitar that I own. But a I've found through research is only for Floyd rose tremolo applications only. Is it possible ton install one on a HT and if so what actions would have to be taken in order to do so and achieve the drop d tuna serving it's true purpose and for it to function properly without any issues? Any information on this subject would be very much appreciated. Thanks

Does good.....NOT GREAT..I can use it though!!

Well....its a screw...so...but it is made from the materials it needs to work.

It lasts a long time....and continues to work...my Wolfgang is a 1998 model...and it is still smooth as ever.

Your general opinion of this product.

Well....a little costly for a screw and a spring..I am positive it cost .95 cent to make and package....but I have one on my Wolfgang and wanted one for my Charvel So-Cal. EASY TO INSTALL AS LONG AS YOU FOLLOW DIRECTIONS....honestly took 5 minutes and I was ready to play...YOUTUBE AN INSTRUCTION VIDEO..

Can't even tell its there...just make sure your bridge is adjusted correctly so that is doesn't dig a hole in your guitar body!!!!....also if you install it right, it is smooth to switch the tunung.

Hits D tuning, so you dont have to tune before those certain songs or change guitars when you play those Creed songs...

Buy the chrome....cause the black wears down too fast from always putting your grubby fingers on it...looks kinda cool on your guitar anyway.

You have to stabilize, flush, or block your trmelo...if you don't, it will fall so far out of tune that you won't be able to use it.

It works!

Well made.

Seems like it will last just fine.

Your general opinion of this product.

Works perfectly. I used it on my Ibanez, with a tremsetter to keep things in tune, but still allow a full floating bridge. Absolutely flawless combination. The installation and setup can be tricky, with the possibility of drilling, routing....etc., but the end result is well worth it. I'm going to buy another set for my other axe.

Switching is a little awkward at first (mostly because I set it down low in the cavity, and need to dive the trem a bit to switch it), but I'll get used to it.

No tone issues.

Looks ok.

Required tweaking, which is to be expected.
