I've done locking tuners on my Epi LP. When working on Bridge or pickup height with a PMS (pickup mounting system) you lose the set of strings. Can't get enough slack to remove the tailpiece. As for the roller bridge, I would not do will a hard tail guitar.

Would be nice to know what tuners and roller bridge you used. Great video.

I really enjoy your videos, you have a pleasant professional presentation style. More videos -- please!

Just wondering, maybe I missed it but why a roller bridge on a non-tremolo guitar?

It's worth noting the more expensive roller saddles have varying size roller slots and can only be fitted screws facing the pick up .Fortunately ours are uniform so can go either way round

why not just remove the tail piece with the strings and put aside?

One drop of 3 and 1 oil for your screws would have done the same job.

It's a 4MM not a number 4 allen or hex wrench. Also you might want to spend the feww buck for a straight edge for checking the neck so you don't have to guess at how far to turn the truss rod. You viewers might really mess up if they just guess like that.
