I recently bought an almost brand new guitar for $45 as mentioned on a recent thread. Now I think I know why the seller let it go so cheaply. I was trying to adjust the bridge downward for better action, but even with no string tension and a special T-handle tool I have for this job, I couldn't move the low E side post up or down. When I tried the high E side, the post was turning, but on closer inspection, it was actually the splined insert turning in the body! It turns out that both posts are either cross-threaded into the inserts, or the posts have different threads from the inserts and were incompatible and should not have been installed. It is the original Epi marked bridge, not something the seller installed. Has anyone else heard of this issue? What a disappointing surprise.
