Nothing compares to standing on the sides of the stage in 1970/71. Listening to Duane crank his 2-50 watters into cabs loaded with Celestions & Cerwin-Vega's. Dickey had the JBL's loaded when the Celestion's blew. It was near impossible to get Celestion's over here back in the day. Those Marshall's took a beating back then. Duane would have Joe Dan load his heads with Sylvannia 6CA7's as they lasted longer and he loved the tone.
