The Mark Five: 25 is born of thoroughbred stock that carries worldwide accolades and is still setting trends with top Artists 35 years after its unveiling. The MARK FIVE: 25, like the MARK FIVE it is born from, is really a collection of iconic amplifiers. There are far too many circuits and sounds to think of it as merely an amp... it’s a living history of Mesa Boogie!

From the groundbreaking Mark I that introduced the world to high-gain with it’s cascading preamp, to the Mark II - the world’s first high gain dual mode channel switching amplifier (and its later siblings that introduced Simul-Classpower). From the MARK III that ushered in the era of 3 channel footswtching performance, to the Mark IV which gave all that power individual control, the Mark Five (and now the FIVE: 25) is the embodiment of the last 45 years of guitar amp evolution.
