Thank you for the Grovers

Exact replacement for my 12 yr old son's Dot. He did the the install and now he wants one of the guitar kits.
Thanks for your great product.
We'll be back.

Love those locking machines

I placed my order on a Friday afternoon, after much measuring, and received them the following Monday. The fit was perfect. I put them on an Epiphone ES175, which is what I use for all my gigs. A lot of guitar for the price. If I need to change any of my other tuners, they will be Grovers! Thanks for the prompt service and the helpful e mail.

Good but touchy...

I got these as a drop in replacement for my non-locking Grovers. The shaft was shorter than the stock ones but I made it work. They lock but my low E and G will still go flat even after I tightened the philips screw on top of the machine head. But its a lot better than having the stock ones back in. I would recommend them still...

Very nice tuners!

On my Les Paul I replaced the stock Klusons with these, and am really happy with them.

SLotted stright into the old holes and fitted without a hitch. Have worked perfectly and the guitar now stays in tune!

Grover Sent Replacements !

After contacting Grover directly with my earlier problem and sending the faulty set in for their review they replaced the set with new ones, all of which work PERFECTLY. A great company to deal with and I will purchase more of these in the future.

I bought this for my SG Standard about a month ago. Simply the best tuner I've ever used. They slipped right in place and HOLD IN TUNE. Barely have to stretch your strings first time you tune to pitch. Highly recommended!

No Difficulties At All

Just got them the other day and tried to make them fail as described by others. No problem at all. Whatever happened in those cases must have been solved. They work wonderfully and look great.

Great Tuners!

I ordered these locking tuners to replace the non-locking tuners on my Dean Cadillac. The difference in this guitar staying in tune has vastly improved. Well worth the money spent. As always, when I placed my order with Stew-Mac it arrived in just a few days, and as always a positive experience. Will definitely order again! Keep up the good work.

Agree with Paul DB

Bought these tuners as retrofits and discovered the same thing as Mr. Broussard below.
While installing the first set I unscrewed the locking knob a bit too far and the whole gear came out of the housing!
After cleaning up all the grease that deposited everywhere I reassembled the unit and proceeded to install two sets on two guitars. I bought four sets and returned two. Every time the strings are changed make VERY SURE that you don't allow the locking knob assembly to fall out of the tuner housing !
Grover seems to have stopped the engineering of this tuning machine just shy of a finished product. At no time should there ever be a possibility of the gear falling out out of a tuning machine !
