Mesa Boogie 1979 Mark IIA Tube Head - UsedThis late 70s tube combo is, like all Mesa Boogie amps, built like a tank! Sturdy and versatile, it's fit for the studio and dependable on the road. Switch between 60 and 100 watts for classic clean or overdriven tube tone. This head is in good condition with some minor scrapes in the tolex on either side. The tubes seem to have plenty of life left in them.
