I understand the general idea of compensated nuts to produce more variance in the string lengths, and thus better intonation over a wider range of fretting positions, but the Buzz Feiten system I see advertised on guitars and as an aftermarket mod that can be done to your guitars seems to be much more. Or is it?
There's the sale of Feiten-system tuners that makes me wonder if there's more to the system. You see this advertised as a feature on tuners from Planet Waves and as a mode that can be selected on tuners from Petersen. What is it about the Feiten tuning system that requires something special of a tuner? What is that something special?
That it's available on locking-nut equipped guitars puzzles me. Is the nut still asymmetrical?
Is the Feiten system just a compensated nut or is there more to it?
