Fit like a glove

Bought a cheaper Epiphone DR-100 and wanted to upgrade all the components to make it better. Tusq nut and saddle and took off the stock tuners and put on a set of Grover 102c Rotomatic Tuners. These were the ones recommended by my sales engineer Paul Eckert. They fit perfectly. All I had to do was fill in the old screw holes from the stock tuners and stain to match the color of the headstock. Then drill the single hole for each new tuner. All in all took about an hour. Looked fantastic. The guitar sounds great and it stays in tune very well. Thank you Paul.

Grover tuners Really Really good!!!

Grovers are great. I am primarily a Violinist. And intonation is very important. The String has to be in tune open to play in tune the rest of the way. And you can not fix the intonation up the string on a guitar , like you can on a violin, frets you know. 18-1 Grovers do the job better than any other tuner I have ever used and I am 62, and have tried most of the tuners out there. Sweetwater is good to do business with. For a bunch of musicians, Ha, Ha, That's a Joke, son That's a Joke!

Good Grovers

What can I say, I like how Grovers work. Very solid good quality and they have never failed me. Dropped these into my old Ventura dread to replace the old plastic ones. Might just be me, but the guitar seems to sound better, if that's possible . I mean, the old tuners still worked ok, but I think that these are so much more solid and make a better connection to the headstock, so this makes sense to me. Sounds better than ever!Thanks Sweetwater!

Grover Tuners

I have found them to be exactly what I was looking for. They have "sensative tuning action" with very little effort. They remind me of the tuners on my D-45 Martin. Pretty much the same in quality. I am completely satisfied with the Grover 102C Rotomatic Tuners. :-) Brad Lee Sr.
