Many guitars come into the shop that were Plek'd at the factory. We've seen some of these that still have fret issues. This scan pictured above is an example of a very expensive guitar from a major manufacturer. It has high frets in prime playing areas. The customer complained of it being buzzy and some notes hardly ringing at all. (mostly on the 4th fret, where the 5th fret is so high the string is hitting it) So while this guitar was Plek'd at the factory, it unfortunately needs more fret work. A Plek job is only as good as the technician who does the job. We are experts at fret work. You won't have this problem with us.
