This killer Japanese Jag has been in the shop a few times before.  One time for a Mastery Bridge install, Lollar pickups installed and again for a Curtis Novak middle pickup install (here and here).  Now it's back in for some finishing touches including new tuners, a Mastery string tree and a Mastery Vibrato (with UFO tip).  All I can say is that this is one of the best, most versatile guitars I've worked on.  The player that owns this guitar is a monster and I love hearing him play it when he brings it by.  Dammit, now I need a 3 pickup (Lollar / Novak) Mastery Jag!
