0121 467, Tuna Black

I’m ashamed I didn’t buy one years ago. There was a lot I couldn’t play on my favourite guitar because of the floating trem and locking nuts. So I finally bought one of these little beauties. Fitting it was very easy and there’s a few good videos online to help. I put a small piece of wood in the back to block the trem (I’ve seen some people use coins) took the E string off, quickly screwed in the EVH d tuna and popped the string back in. Pull it out and tune to a D then push in just enough to lift the fine tuning screw then use the hex key to fine tune the E. I take a bit of fiddling to get it just right, 10 min or so. But now it’s perfect and I can drop to D and back to E in a second without effecting the other strings.

Awesome. works well once set up!

Excellent

Item arrived early, but small spring was missing from the package! I managed to re-use the part from my existing D-Tuna, but it was annoying!

Lot of Money for what it is, not easy to set up on my guitar, took it off not used since.

The EVH D-Tuna Drop D Tuning System is a highly efficient and straightforward tool for any guitarist who wants seamless drop-D tuning without having to manually tune the low E string down to D. Developed by Eddie Van Halen, this clever device is compatible with most Floyd Rose-style tremolos, making it a perfect solution for players who love the versatility of both standard and drop-D tuning. Installation and Setup Setting up the D-Tuna is straightforward, though it does require a bit of fine-tuning. It involves removing the existing fine-tuner on the low E string and replacing it with the D-Tuna. The installation can be done by most guitarists with basic tools, but if you're unfamiliar with Floyd Rose systems, a guitar tech might help ensure a smooth setup. Performance Once installed and properly set up, the D-Tuna performs impressively well. Switching between standard tuning and drop D is as simple as pulling the device in or out. This quick toggle is especially handy in live settings where a quick tuning change is essential. The tuning stability is commendable; it holds well with little-to-no deviation, thanks to the design that prevents wobbling or accidental shifts during intense playing. Compatibility and Limitations While the D-Tuna is designed to work with most Floyd Rose bridges, it’s best suited for setups without a floating bridge, as a floating bridge needs to be “decked” or stabilized to allow the D-Tuna to function optimally. Some players may find this limiting, especially those who prefer full-floating tremolo action. Pros: Quick Drop D switching: Effortless switching between standard and drop-D tuning with a simple pull or push. Solid tuning stability: Stays in tune even during heavy playing. Durable design: Built from quality materials to withstand intense use. Cons: Limited to Floyd Rose-style systems: Not suitable for all bridge types. Requires “decked” bridge setup: Users with floating bridges may need to adjust their setup for full functionality. Overall Verdict The EVH D-Tuna Drop D Tuning System is a fantastic, innovative tool for players looking to make quick tuning changes. It’s a bit of a niche product but invaluable for Floyd Rose users who want the versatility of both standard and drop D tuning. The solid construction and ease of use make it worth the investment for live players and metal/rock guitarists who switch tunings frequently.

Excellent product and design. Functions flawlessly when installed and setup correctly. Highly recommended for any Floyd Rose bridge rockers who needs an instantaneous dropped D tuning. The “D Tuna” rocks just like EVH!

Once set up works great

As long as it's set up right and you have a deck only Floyd Rose, it works perfect There is a fine set screw so make sure that your low string is set all the way up so your tuna can slide in and out without scraping the threads Took two times but it said perfect and it works every time I use it. It's been many months now. D to E no problem
