i would recommend people who plan on getting tone pros locking tail piece studs to try and get the vintage steel studs, i got those for my guitar and they where great replacement over the stock brass studs that come with the current gibsons, the original bursts came with steel studs as well. they add more ring and sustain to the guitar.
i also got the locking AVR-2 bridge for my les paul, they do also make one for Nashville style bridge, that was also a good improvement over the factory ABR-1 bridge, the saddles are much titer fit, and they dont vibrate like some in the gibson bridges, and the retaining wire is for looks, in which i have removed on my bridge.
over all great products.
its all a matter of principle...
