Great for 12 strings

By Lithos from Birmingham, AL
(Customer's Reviews) Monday, June 02, 2014


I bought 2 sets to put on a 12 string a few years ago. Replacing strings on one of those is a major hassle, and these make it easy. They were missing from StewMac for quite a while and, although I don't expect to be getting another 12 string, it's a comfort to have them back.

Great!

Very sturdy and precise tuning gear. I think it's one of the better tuning machines out there.

Awesome Tuners!

I love these. The work amazingly well. The thumbscrew lock mechanism is excellent. The quality is top notch!

Excellent product, but wished I had purchased gold!

Purchased the chrome version, and am very impressed with the quality. Tuning seems to be very stable, as long as the peg heads are tightened securely. Very easy to mount, given that these have 3 little prongs that will press into the guitar's wood to locate when securing screw holes need to be drilled.

They are very solid, provide a nice weight to the headstock.

Good.... but not the best

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.

solid upgrade

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

Grover Mini Roto-Grip's Blow Sperzels away!!!

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!



Sincerely,

Dave Grim - Owner/Builder

High Quality, Precise and easy string changes

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.
