I don't like to bore people with my life history but I have been playing guitar and bass for over 30 yrs. My father was also a guitar player and his band opened for the Allman Brothers , Grateful Dead, Jimi Hendrix, Procal Harum, Captain Beefheart, 13th Floor Elevators and Fleetwood Mac with Peter Green etc. I put as much creativity and innovation in the pickguards that I make as possible making each one different and adding features that allow you to get as many sounds combinations as possible.
