With uniquely inspiring Tone and a layout that’s intuitive and easy to navigate, it’s no wonder the Express Series has become one of Mesa Boogie's most popular amplifier lines. All-Tube and hand-built in their only shop in Petaluma, CA, the Express Plus 5:25 offers genre-defining sounds, near-limitless versatility, and unbeatable value that others can only imitate. How do they do it? Mesa Boogie has been doing this since 1969 with many of the same people…it’s Mesa Boogie's Experience – and there are no shortcuts to this level. The Express Plus 5:25 features many exciting features that take it even closer to the flagship status of Mesa's award-winning MARK FIVE.
