I just had the pleasure of spending a weekend at the Puget Sound Guitar Workshop's winter retreat in Port Orchard Washington with about 140 other players, including John and Becky Knowles. John has been coming out to PSGW from Nashville for over 20 years to teach. He is a true gentleman and as nice a man as you'd ever hope to meet. His style is tasteful, subtle, and absolutely stunning.
