Re: gibson R8 VOS vs. normal... whats the $400 difference?
PLEK is a new expensive machine on the market that provides the BEST fret job and setup possible- basically the guitar is put in this machine with the strings tuned to pitch, laser scanners scan the fretboard, fret heights, and neck bow, then they can program how they want the frets shaped and leveled. Once the parameters are programmed, the machine dresses, levels, planes, etc.. the frets. EVERY guitar will come out with the same, identical, consistent setup. The machine can also be programmed for different setups.
To get your guitar PLEK'd at a shop that has a PLEK machine normally costs about $300 plus the setup. The machine is very expensive, I think $150,000.
Heritage started using it to help with their inconsistent and poor setups. I guess Gibson has done so as well.
