The Eddie Van Halen D-Tuna is a drop D tuning system designed to adapt to a double-locking tremolo such as a Floyd Rose or Floyd Rose-licensed trem. A low-profile, double-locking tremolo may require modification. The EVH D-Tuna attaches to the low-E string saddle-locking screw. Once in place and set, all you do is slide the mechanism — in for E, out for D.
