Allparts EVH D-Tuna Drop D Black

Designed to work on a dive only bridge, so if you want to put it on your floating floyd rose, you have to either:
1. Rise the bridge from bottom strings A LOT.
2. Router a cavity for the D-tuna in to your guitar body.

Easy install. Works well, but needs to be operated with tedious care, as it is possible to displace the unit slightly. And that will put your instrument out of tune.

Always press down on the unit before sliding it in or out. Majeu sure the unit is perfectly in place. Then check the fine tuning. You'll find the unit is NOT in place correctly if the tuning is off noticably. If the unit is its place, only minimal fine tuning is needed.

For floating trems, use a Super-Vee MagLok to stabilize the bridge first. That works.

The installation of the kit was pretty straightforward and fast.
Tuning stability stayed exact the same as before, and droptuning with kit was spot-on.


So if one likes to tinker between Standard and drop-tuning on the same Floyd Rose equipped guitar, this unit makes things a lot less complicated.

Only downside I can think of, is that it limits pullups with Floyd in most cases.

So all in all, does the job it's made for.
