Mesa Boogie Express 5:50+ 1×12 Combo
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?
But what’s amazing is this – each power mode has it’s own tone-spawning operating class and wiring configuration! Choose the full power mode of 50 watts in the Express Plus 5:50 for Class AB running in a Push-Pull configuration for punch, authority and headroom. Or, kick down to 25 watts for Class A Pentode and a more silky, vintage voice with enhanced clip potential. And for the ultimate in low wattage power, knock it down to the 5 watt mode… now you’re running one tube in Class A Triode wired in a Single-Ended configuration.
Obviously we were thankful the patent office saw the possibilities and rewarded our efforts with a patent, but what excites us is the look on players faces when they hear and feel this power section magic for the first time.
RICH ALL-TUBE REVERB ENHANCES THE SPATIAL QUALITY OF YOUR EXPRESS PLUS
Our rich All-Tube REVERB enhances the spatial quality of your Express Plus 5:50 and each Channel provides an independent Reverb Mix control so you can get the perfect blend of this beautiful effect for each of your footswitchable sounds. The Reverb effect can be triggered on and off via the included Footswitch.
The Express 5:50 features a dramatic enhancement in the EQ department with the inclusion of our time-honored 5 Band Graphic Equalizer! The sliders are added in addition to the original Channel Assignable PRESET contour controls and you can now choose whether you want to use the Sliders or the PRESET in each Channel with the EQ Assign mini toggle. The EQ, whether set to call up the Sliders or the PRESET controls, is also footswitchable and can be called up at any time via the Express Plus Footswitch.
Outboard Processing is handled by the series EFFECTS LOOP, keeping patching to a minimum and protecting tonal integrity a priority. The Express Plus amplifiers are compatible with most good quality processors and using this feature for all of your rack-type effects will produce gratifying results.
