What We Think
Condition: Very Good
This Mesa Boogie Stereo 2:90 Simul-Class is an iconic 2U rackmount power amp that delivers massive stereo headroom, articulate punch, and legendary tube muscle. Driven by eight 6L6 power tubes and three 12AX7 preamps, this 35-pound heavyweight puts out 90 watts per channel utilizing Mesa's patented Simul-Class topology, which combines the warm, musical detail of Class A with the high-output horsepower of Class AB. Each channel offers independent Volume and Presence controls alongside remote-switchable voicing modes, including Deep for enhanced bottom-end, HalfDrive for reduced power saturation, and Modern for aggressive high-gain bite. Built with internal fan cooling, multiple 4-ohm and 8-ohm speaker outputs per channel, and an ultra-durable chassis, this professional power engine remains a gold standard for rack-based rigs seeking pure, uncompromising tube authority.
About Manufacturer
Forty-five years and thousands of satisfied customers later, MESA/Boogie® Ltd. hand-builds the fifth generational offspring of that pivotal amplifier (and many more) now known around the globe as the MARK I Boogie®; the world’s first high gain, high power, compact 1x12 amplifier. That revolutionary little combo is the “missing link” in amp design... the pivotal nexus between Vintage and Modern guitar amplifiers. When it comes to amplified guitar, there’s really just two epochs… before Boogie, and after Boogie.
