Watch the Pinchy online guitar lesson by Jeff McErlain from 50 Blues Guitar Licks You MUST Know
Rev. Billy S. Gibbons and Roy Buchanan are the kings of the pinch harmonic. Just listen to the solos from Billy's La Grange or Roy's “Pete's Blue” for the play book. Pinch harmonics, also known as a squealie, allow you to get harmonics anywhere. It cancels the main note called the fundamental and lets a high harmonic ring out and man does it sound cool. The technique takes a little time to get mastered, but it is much like riding a bike. Some overdrive on your amp really makes these notes sing.
