Hey everyone. I received a Michael Kelly Dragonfly 5'er I purchased from GC used. I got it for a great price, and it's in excellent condition. There is only one thing about the instrument that I do not like, and I'd really rather not return it. The G and low B strings have some terrible buzz on frets 13 and 14. It's almost bad enough to call a fret out. The note dies almost immediately and the clank is very disrupting. All other notes on the bass sound great. Is a fret job the only way to fix this issue? The action is not really low, the neck does not appear to be twisted and the fret itself does not appear to be coming out of the slot so I would assume its a high/low fret. Generally, is swapping or recrowning just one or two frets an expensive job? Any other theories on why this is happening would be appreciated as well.
