He has been around a long time.....I believe he was one of the early endorsers, right after Kim Wilson, Greg "Fingers" Taylor, Paul Lamb, etc. of the Sonny Jr amps.
Pierre's precise phrasing is fantastic. Very clear and concise. His minor playing in third position and using minor tuned harmonicas is as good as it gets. He is a role model for me in minor playing. Blues for George Baze is a great example.
