    Well worth the price.

    Replaced my puke green machine heads on my ES 135 with these and I am very happy. Fits like a glove...

    Time for a change.

    I liked the ease to install. The quality appears top shelf. Forty years of heavy use destroyed my original machine heads. This was a necessary change to maintain tune. I am pleased with the decision to purchase from graphtech. I'll report back if they fail to function as intended.

    They are very nice tuners

    Hello! I put these tuners on my Jackson JS22-7 string. The post height is subtly lower, but they fit very thick gauge strings and lock. The post height is probably more optimal. I wish I knew that it was possible, and desirable, to buy the black colored adapters and that I would have to use adapter plates. I'm not bagging on the adapter plates - they are an advance, and made installation super easy. I just wish I had the black ones. It stays in tune well. Good stuff!

    Fantastic machine heads

    Fantastic tuners which were a straight swap on my FMT Telecaster. Took all of ten minutes to install and restring. The stock tuners were OK but these are so much better. The ratios of the gearing makes a huge difference. I'm planning to get some for my other guitars. Utterly fabulous!
