In this review the Allparts BP-2020-010 EVH D-tuna is evaluated as a simple, purpose-driven accessory for players who use a Floyd Rose style locking tremolo and need fast, reliable drop D switching. The bottom line: this mechanism is for guitarists who want a compact, durable solution to drop down a single string to D without re-tuning the whole guitar. The reviewer found it true to its description: manufactured in the United States, straightforward to install if you are comfortable with a Floyd Rose tremolo, and an effective way to add the classic EVH quick-drop function to compatible bridges.

Key Features

• Drop D Mechanism Compatibility: Designed specifically for Floyd Rose style locking tremolos, it provides the familiar EVH D-tuna functionality on the low string.
• Single Item Package: Ships as one complete unit so customers receive everything needed to add the feature to one guitar without excess packaging.
• US Manufacturing: Made in the United States, offering consistent build quality and parts sourced to a known origin.
• Compact Dimensions: The package is small and light with compact dimensions that make it easy to store or ship and suggest a compact mechanism footprint.

Who It's For

The Allparts EVH D-tuna is aimed at electric guitar players who already use a Floyd Rose style locking tremolo and want the convenience of instant drop D without loosening the other strings. It is particularly useful for players who perform songs requiring quick low-D transitions or who appreciate the hardware used on Eddie Van Halen style setups.

Those who should look elsewhere include players using non-locking tremolos, fixed bridge guitars, or those uncomfortable performing a hardware installation on a locking tremolo system; a professional setup or a technician may be advisable for first-time installers.
