I was pretty happy with the Mastery I had on for the past decade (wait, that can't be right...is that right?), excepting the orthodontia aesthetic. Mine has been solid AF. But the Tuffset looked smart, and intonation looked easy, so when the OSG discount came up, I thought, why not.
The guitar seems more resonant than before. Feedback comes sooner, but in a very pleasant way. It's only been on for a couple of weeks now, but I see no reason why it would come off.
I am slightly troubled by the ability to knock everything out of tune be leaning HARD on the bridge, but that's a me problem. Installation was a bit of a grind. I backed out the screws to where a couple of the tiny nuts on the underside came out. I had to wear TWO PAIR OF READING GLASSES at the same time to get them re-installed (again, a me problem)...but yeah, pretty happy with the Tuffset.
