I recently got a LP custom by Epiphone and the high frets were buzzing. I did what I could, including a fret level and a a couple truss adjustments. I could not resolve the issue and took it to my local repair guy. He told me the guitar had never been set up or, if it had, it was incompetent. I was too embarrassed to tell him I had attempted to set it up myself. Ive set up all my own guitars for years so, had no idea I was doing it all wrong. At any rate, twenty dollars later my Epiphone is sorted out. I wont hold it against the guy that he unknowingly insulted me, as he clearly is more competent. On the plus side, he let me play a 1966 Tele while he worker on my guitar. Damn sweet but some really crazy mods.
