Kluson MLS33C Lockheads

Perfect replacement for a PRS SE. Unfortunately the fact that you need a screwdriver to lock the string has two issues: 1) You have to carry a screwdriver with you 2) You can't really tell if the string is as tight as it should and there is always a possibility to overtighten the screw and break the string as soon as you put enough tension to it. I also think that the edges of the wholes where the string gets in are a bit sharp, which might also cause the string to break.

These machine heads are high quality. They feel sturdy and durable. I am sure they would have been a great upgrade for my newly acquired HB CST24, however shaft length is too short for the CST24. I was really gutted cause I really wanted to install them.

Only con for me (and why the 4*) is the lack of info on specs incl shaft length which i didn't know was going to be an issue.

I bought them to change the tuners in my PRS SE 245, original tuners were not trustworthy, this ones are great in quality but slightly smaller so you struggle to fit in the strings, but it works. Just be aware of what shaf's size you need.
