Graph Tech Archtop Bridge PS-7551-N

i recieved a broken 1950s jazz guitar which needed refinishing and repair, it had no hardware so i set about finding the parts to finish it, having purchased graphtech nuts before i knew they were of good quality and worth a go at putting on my newly restored guitar, it was incredibly easy to fit, just drop it in the right place on the guitar, make sure intonation is correct and adjust the string height, the bridge adjusts to any archtop shape as the bridge has some flex to it which is genius, now i can pretend to be george benson but without the talent, i play lots of wrong notes and call it jazz, poeple have actually commented on how great the guitar sounds acoustically, it has nice harmonics and you can feel the body resonate, im sure this is because of the bridge transferring the string noise through the body so well, graphtech make great parts if you need upgrades or replacements, a great purchase

While the plastic parts seem to be fine, the threaded posts and thumbwheels were a very poor fit. One of the thumbwheels had almost no knurling on the edge - rather like a very old coin. It was so loose on the post that it would not have taken the load from the strings for very long. The other thumbwheel had proper knurling but the fit wasn't much better - it too was loose.

I was able to use the threaded posts and thumbwheels from the bridge that I was replacing - remarkably, they were in far better condition after 30 years use than the new Graph Tech ones.

Perhaps I was unlucky or perhaps there is a quality problem with the item.
