The Key

I read all of the reviews of this tool and bought it anyway; I'm glad I did. This tool works great. Of course you can do a setup without it, but it really does speed things up. If you understand what the tool is for then you can figure out how to use it just by looking at it. It works on original floyds and the floyd rose special too. By the way, the reviewer who thinks you should be able to use the tool without loosening the string keeping the string tuned to pitch must not understand that the pitch of a guitar string changes when the tension on that string changes...come on man!

Great Idea, but needs improvement.Thumb wheel hard to turn when tuned to pitch(one review suggested you should loosen strings before adjusting,kinda defeats the idea)Clumsy to install and remove.

A video showing how this tool works is needed. I don't understand how this makes intonating an original Floyd Rose easier. When the strings are under tension, loosening the nut clamp and using the key to intonate tends to "push" the saddle screw down instead of pushing the saddle forwards or backwards.

If you loosen the tension on the strings before you use the key, what is the point of the key? You might as well just move the saddle forward or back a millimeter at a time and retune until you get the intonation right. Maybe I don't understand how the key works, but from the other reviews it seems a lot of other people don't understand it either. It's Stew-Mac's job to make sure its customers understand the tools it sells. So lets see a tutorial video folks!

The tool is not really practice, the intonation is more easy without it. The Key does not make a good job because when it is instalated in the Floyd Rose the tuner changes, the saddle is colocated in one different level, it makes that intonation change with The Key is putted and it is putted off.

The Key works great easy to use, fast, and reliable. When your working on an Original Floyd Rose(Style) equipped guitar do yourself a favor and use the key.

En su dia (4-22-2011) hice una valoración negativa del producto. Al cabo de unos dias recibi un correo pidiendo disculpas y indicandome que en breve recibiria un "The Key" nuevo sin coste alguno y pasados algunos dias recibie un "The Key" nuevo sin cargo. Todo y que haga el comentario ahora, el producto lo recibi hace bastante tiempo y todavia no lo he utilizado. No puedo valorar el producto al no haberlo utilizado, pero si que puedo dar un 10 al servicio de atención al cliente.

Poor value for money. Waste of time and money totally useless, nonfunctional!

If you use this tool correctly you achieve perfect intonation. Of course you have to loosen the string tension completely...would you actualy try moving the string saddles with your fingers at full string tension? Apparently some of the other reviewers would. This tool is great. It is not a tool that lets the user completely slack off!!! Wish they would develop one for ibanez lo pro trems. Final thought...godsend tool.

I've had this tool for a while, I bought it in the event the guitar tech I was using needed it on my Jackson Soloist, he declined. When I finally bought a strobe tuner, I decided to try it on a new acquisition.
This tool works perfectly. You snap it in place, screw it open until it makes contact with the bridge and screw head, then undo your allen key lock bolt and start adjusting. Holds tension going forward and backward on the saddle travel. I guess the only improvement I would make to it is to make the knob longer so that it extends past the body, and knurl the knob where your fingers turn the knob for added grip. Great tool!! My intonation came out perfect, by the way!!

Poor value for money. Pain to work with when strings are in tune / under tension.
I ended up using the bottom catch as the hook, pulling the entire assembly with my thumb and index finger.

Something much simpler, similar to Moody Spring Pull Hook tool [sold by StewMac], would be considerably more useful
