I bought them to continue the upgrades on my TE-20 HH (so far swapped out the nut, the pickups and installed strap locks).
I usually take my guitars to my tech, but the installation is really easy to do yourself at home.
Just loosen the High E and the B strings, install the first string tree, then tune up. Only then switch to the D and G strings for the next string tree.
I did it this way to not lose all the tension and mess with the guitar neck/intonation..
Also, I used the original screws I had on the guitar, as the ones that come in the kit are a bit too long.
I would definitely buy them again, as I need to install them on two other guitars, and for my future guitar purchases they will always be added to the basket by default, just like I do with the Tusq nut.
