Jerry Greenberg sets up every MacKenzie & Marr guitar before it goes out the door. Occasionally he'll re-adjust that setup at customer's request. Here he's lowering the action for a finger-style of play.
Jerry is our secret weapon. He's been building and repairing musical instruments since....well....since a long time. No one can duplicate his work with the same skill and experience.
He also builds and customizes motorcycles, plays a mean sitar (when Ravi Shankar left the Indian pavilion at Expo 67 guess who was hired to take his place) and knows just about every good place to eat between here and everywhere else. Can you say Renaissance Man?
