The Mesa Boogie Mark Five 25 head is a compact, all-tube amp with signature Mesa tones and a plethora of features making it a pinnacle of versatility. The clean and dirty channels take you through the history of Boogie, from the Mark I's boost to the Mark II and Mark IV's lead tones. Shape your tone with the legendary Boogie 5-band graphic EQ, add some ambience with the tube-driven spring reverb, and completely change the sonic personality of the amp with switchable output wattages and operating classes. An onboard headphone amp for silent practice and Cabclone DI for direct recording and cab-less live rigs round out the feature set to make the Mark Five 25 one of the most flexible amps on the market.
