Hey guys! I figured all of you would be interested in this. I was just reading that Grover released new tuneing keys in the 505 series. They are made to replace the old original style fender keys without having to make any modifications. I wouldn’t mind trying these on my Eric Clapton Strat. Most of the ones I seen you had to drill holes or do some kind of mod. I figured I would show you guys and let you know. I posted the link below. This just hit my mind also but do you have to do any mods with the Graph Tech Ratio keys or do they have a plate for replacing the old original fender keys?
