I was expecting the guitar tuners to work well since I had purchased another set of tuners for another electric I had. I was not disappointed! Installation was easy and the tuners work as specified.

Perfect!

Retro style and GraphTech quality. The ratio engineering of each tuner fixes tuning issues and allows for a subtle tweak to get that string to pitch! Love em!
