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.

What is your opinion of this product?
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
What is your opinion of this product?
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!!
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..

It works!
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.

not very acurate
Your general opinion of this product.
Cool concept. Could work. Needs tweaking. Make sure your bridge is stabilized. My bridge is blocked and I found it not accurate. After you engage it, your guitar needs tuning if your ear is somewhat decent. If the bridge is blocked anyway save some money and just tune the guitar manualy.

Don't drop your cash on a D tuna...
Your general opinion of this product.


QUALITY:
seems alright. It's metal...

FEATURES:
It provides a battering ram for your guitars' body whenever you pull on the bar.

EASE OF USE:
It's easier to use your bridges' fine tuners to drop to d then to install this unit. It does go from e to d and back quicker than using the tuners though. Easily allows you to dig a gouge in your guitars finish while simultaneously preventing you from pulling your bar fully.

VALUE:
I'd rather save my money and use my floyds' fine tuners than purchase this item.

SOUND:
Maybe, but just maybe adds a slight bit of sustain to your low e string by adding some mass to the bridge.

Good if it fits...
Your general opinion of this product.


QUALITY:
In order to make this tool really ultimate, the creators need to take into account the Jackson guitar and others that have the fine tuners in a different location.

FEATURES:
Very handy tool for the snap tunings back and forth.

EASE OF USE:
Couldn't really install it...sadly

VALUE:
Decent price, wouldn't mind all that much if it was cheaper.

SOUND:
I gave it a 5 just because if you do prevent the bridge from moving , theoretically it should not disturb the sound, so thats a good point.

STYLE:
Rock, from the Van Halen era

MUSIC EXPERIENCE:
Gigs and lots of practice

OVERALL:
I can't give an overall review since it does not fit my guitar properly, if only I had found out about that sooner after trying to install it.
