This amp is in excellent cosmetic condition, although there are some minor obvious condition flaws from years of typical and expected use. While his amp is smaller than any Fender amp head ever made, but keep in mind, it is about twice as loud (and heavy) than Fender’s gigantic Dual Showman Reverb. Perhaps the most over-built and solid amp ever produced, MESA Boogies are extremely high-quality and were destined by design to outlast the competition. Also, the majority of Boogies were covered with a black tolex, which makes those with a wood cabinet or cream vinyl exterior more desirable. Piggyback versions were seldom featured in advertisements or catalogs, as the 1×12″ combos were more commonplace. While MESA Boogie Mark II(A)s are fairly rare to begin with, finding an amp head is increasingly more difficult. Additionally, the amp sports 2-channel footswitching, reverb, a fetron/12AX7 switch, and a 5-band graphic EQ. Thankfully this particular example features Simul-Class, which allows the amp to be switched between 60 or 100 watts.

The amp sounds really great, and is quite loud. It is in perfect working condition, and all potentiometers and sliders were properly serviced with contact cleaner. As briefly mentioned, it is all original, and still retains ALL of the original tubes. This MESA Mark II is extremely nice: it has never been modified, fixed, repaired, or broken. This classic MESA is a particularly rare version, is in great original shape, and sounds absolutely incredible. This rare 1979 MESA Boogie Mark II amplifier head (60/100W Simul-Class example), serial number 3866, features a rare blond tolex with corresponding wheat grill cloth, and remains in excellent original cosmetic condition.
