Mesa Boogie Mark Five: 25 Guitar Amplifier Head, Black Bronco

The Mesa Boogie Mark Five: 25 Guitar Amplifier Head in Black Bronco packs decades of high-gain evolution into a format that’s built for modern players who demand performance without excess weight. Weighing only 16.5 pounds and measuring 14 inches wide, this compact amp head distills the legacy of the Mark Series into a versatile two-channel platform, delivering six distinctive modes that pay homage to Mesa’s storied past. The Mark Five: 25 captures the essence of the legendary Mark IIC+, Mark IV, and Mark V preamps, now paired with an EL84-powered 25-watt output section for a fresh, agile take on Mesa’s signature voice.

Each of the two fully independent channels features three mode selections, offering everything from shimmering cleans to ferocious lead tones. Thanks to its Dyna-Watt power section, players can toggle between 10-watt and 25-watt settings for tighter control over headroom and compression. The onboard all-tube spring reverb and fully buffered effects loop provide a flexible foundation for both stage and studio needs, while a master volume control and selectable wattage give even more tonal sculpting options.

Around back, the Mark Five: 25 features versatile I/O, including 8-ohm and dual 4-ohm speaker outs, making it easy to match with different cabinets. It ships with a 2-button footswitch for instant channel and mode changes, and a durable slip cover is included for protection between gigs. The Mark Five: 25 is not just a tribute to Mesa’s past—it’s a high-speed, surgically precise tone machine built for today’s guitarist.
