Graph Tech Ratio Tuners
These tuners are great, I put them on a guitar where I use a lot of alternate tunings and it is great that each string reacts the same to tuning. They are also very stable. Only complaint is the package does not include the Fender 2 pin style invisomatch plates, all the others, just not the ones I needed.

Graph Tech Ratio Locking Tuners
Replaced EZ-Lock tuners which don't lock at all and are sloppy with Graph Tech Ratio Locking Tuners. These are very nicely made, super clean install and look good. Most of all they are nice to use, no slop and quick to tune and hold it..
