This 335 came back in as the owner was complaining about a dead spot when the strings were bent on the G and B string near the 12th fret. Everywhere else the guitar was without issue and it seemed to just be this particular bend that was the issue. I found so high frets with the fret rocker but it wasn’t until I levelled the frets that I saw the actual issue was a dip from around the 3rd fret to around the 12th.
