I swear since i picked up my rg550, my original edge bridge has not stayed in tune anywhere like it does since getting this. i know its just a tool and its hard to think this can make a major difference. but my smaller allen keys always stripped real fast and apparently never tightened the way they do now. im not sure if its cause they're a little longer than the ones i've used.... but these get the tightness i need. without breaking strings from the nut! grab a few
A guitarist should always have a few of these on hand for action adjustment, locking tuners, and floating tremolo style bridges. These can handle high stress without stripping the tool.
Well, I don't exactly know how to review an Allen Wrench, since they all work the same. However, the long end is made longer, making it easier to make adjustments.
