I got this Harley Benton DC Junior a few years ago and it’s been my main axe since.

Only issue is it has the worse tuning stability of any guitar I’ve owned, Not only going out of tune but getting it to correct pitch can be spotty in the first place.

Any ideas for replacement tuning machines? I’ve already replaced the nut with a graphtech one a while back and it only slightly helped when tuning up. I also don’t mind drilling new screw holes if need be.
