Locking nuts and my Gretsch

I have locking tuners on my Sparkle Jet and it stays in tune fine. I just really worked on the nut a lot over the years.

I also have a non locking nut guitar with a really old Floyd Rose without the fine tuners that is a great trem and it works fine.

In my experience using 3:1 and some graphite powder (you can get it for about $3 at Hobby Lobby with the pinewood derby cars) on the saddles and nut along with a properly cut nut and saddles will work pretty well. Add in locking tuners if you need them. The tuners can change the feel of the guitar so it's kind of a compromise (sometimes!).

Also, while I'm on the subject of graphite, adding a bunch to some of that Hobby Lobby arcylic paint that's about $1 a bottle makes great shielding paint, which ScrewMac and many others sell for $30+.

Anyways, as long as you bought a Floyd Rose #3 nut and have a modern Gretsch the locking nut would work fine if that's what you want to do. I believe a lot of the new Gretsch guitars have a 12" radius. Simple install.

Fun fact for you **** rocking cowboys. C.C. DeVille played a 6120 on the solo for Something to Believe In.

I was prob in 8th grade or a freshman when that came out and was kind of bothered by that because I had been collecting old Gretsch and Gibson guitars, which were kind of affordable at the time even for a kid mowing lawns and I had always hated hair metal.

 

It has been done before. French guy, I think he was still on the forum when I joined a decade ago.
