A 1991 Mesa Boogie Mark IV tube combo amp. It has a few scuffs and scrapes but is in great overall shape for its age. This is an early model with the original EV speaker...a big step up over the Celestions that were used in later Mark IVs. This amp has been serviced and tested. It is fully functional and sounds fantastic. Includes original footswitch.

From Mesa...

Legendary in performance, these giant killers continue the legacy that first defined Mesa Boogie. Their compact size, stunning power and ultimate versatility have served legions of proud owners who see the Mark IV as the culmination of guitar amp evolution. The fifty thousand, II, III and IVs still in active duty are testament to this heritage.

Three Big Sounds...with individual control and total conviction: Rhythm 1 feels bouncy and shimmers with freshness. The Lead Mode is blistering high-gain focus. And Rhythm 2 covers that elusive middle ground. This mode alone can produce an alternate Clean, a purring Blues or a grinding Crunch.

All this and the elusive magic of Simul-Class...our patented way of enriching a power section. Think of it as two different power amps working simultaneously. One extracts the juice of Class A sweetness while the other delivers the high power punch of Pentode Class AB.
