I bought these Harley Benton Locking Tuners as a replacement for an old Squier Tele I had. The stock tuners were cheap, really cheap, so these Harley Benton once were a great upgrade!
I had to enlarge the holes a little, because the HB tuners had a slightly bigger portion, but that was no problem.
After installing them, I could really see a big difference - the tuning stability was better, and the locking parts did a great job of keeping the strings in place.
I would surely use these again, for an upgrade!
Highly recommended.
