Pleased to offer an early Mesa Boogie Mark 1 guitar amplifier in excellent condition. 

These first generation of 3,000 Mark 1s were made from 1971 to 1978; this is serial number 1869. 

All original, sounds great clean with or without the EQ engaged and the push-pull gain gives that perfect Mesa Boogie overdrive with clarity and sustain. 

As Carlos Santana first told Randall when he played his prototype in 1969, “this thing boogies!”
