I would change my bridge with a tonepros AVT2. I want to change Aldo the actual studs and inserts (bushings/anchors) with the tonepros locking ones. The bushings/anchors on the PRS Se are Like the Gibson, they are 1/2" ( about 13 mm), aren't they? Could you measured it? I nave measured with a caliper and they were about 13 mm. But the thread in our inserts isn't like the Gibson (it isn't 5/16-24", isn't US thread) it is metric M8 x 1.25. Now the problemi: the metric kit of locking studs (bushings/inserts + studs) sold by tonepros has bushings that are 7/16" diameter, so they are to small for our holes. What can i do? I would install the studs and bushings.
