Grover Roto-Grip Mini Locking Guitar Machines

I put these on a Strat and they work. One of them fell apart the first time I used it but they seem to be fine now. I will always go for Sperzels from this point on.

This product exceeded my expectations!!they're silky smooth,don't slip and look awesome on my new pinecaster!!

A breeze to install, use and string up, and the 18:1 ratio makes for easy tuning. Very pleased.

These tuners are fantastic! I purchased these and installed on my Franken Steinocaster as replacements for the Sperzel Locking tuners that were installed previously. No comparison whatsoever. If you are currently using Sperzels, replace them immediately with these, they are so much better it's ridiculous. The Sperzels are 12:1, these Grovers are 18:1,you figure it out.

The ability to fine tune with these is so much better. This is the single best mod I have done to any of my Guitars. I have non-locking Grovers on one of my other guitars and they are great too. I will use Grover's exclusively on all my guitars and in all recommendations I make to my clients.

Thanks again Stew Mac - I can always count on you folks to deliver the best products at a great price with excellent service to boot. Fanfreakintastic!

These are easy to fit and use and are of a high quality. 18:1 gear ratio is what I always look for in a tuner.
