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.
