Mesa Boogie Express 5:50+ Combo Guitar Amplifier

Mesa Boogie

With uniquely inspiring Tone, the Express Plus 5:50™ has become one of our most popular amplifiers. All-Tube and hand-built in our only shop in Petaluma, CA, the Express Plus 5:50 offers genre-defining sounds, near-limitless versatility, and unbeatable value that others can only imitate. The Express Plus 5:50 features several exciting features that take it even closer to the flagship status of our award-winning MARK FIVE®.

Both Express Plus™ models use the same super versatile, tone-packed preamp featuring two fully independent Channels, each of which contain two style enhanced modes to choose from when creating your footswitching preferences. Channel 1 hosts the blooming low-gain sweetness of CLEAN or the snarling mid-gain percussiveness of CRUNCH and covers the rhythm territories.

Channel 2 offers a different face to mid-gain with the howling honesty of BLUES or a high-gain adventure through the searing layers of molten harmonics in BURN. Together these two inspiring modes invite years of solo exploration.

MULTI-WATT POWER AND OUR FAMOUS 5-BAND GRAPHIC EQ

Both Express Plus models, the bouncy 25 watt 5:25 with its 2xEL84 9-pin power tubes and the bolder 50 watt 5:50 running 2x6L6 octal-base pentodes, now feature our patented Multi-Watt™ Channel Assignable power switching. This valuable feature allows you to run the output tubes in your choice of three different wattage ratings per Channel – very cool right?
