Mesa Boogie Mark Series

The Mark I had two channels: The "Input 2" channel, voiced like the Fender Bassman, and the high gain "Input 1" channel, which produced the overdriven "Boogie lead" sound used most notably by Carlos Santana on Abraxas, and by The Rolling Stones' Keith Richards and Ron Wood, who used the amps live and in the studio from 1977 until 1993.
