MESA/Boogie Express 5:50+ 50-watt Amplifier Head

It’s been more than 25 years, two generations of guitarists and several musical trend-cycles since the Dual Rectifier first unleashed its crushing wall of gain on radio. In that time many have mimicked, modeled, dissected and plagiarized it, but it remains firmly planted at the center of heavy music; a Rock icon.

 

Over a decade ago the Recto underwent a massive facelift that greatly expanded its versatility and took what was a 2 Channel amp aimed squarely at high gain only – to a 3 Channel amp capable of roaming any style confidently.

 

While still leaving the widest, deepest footprint in heavy music, the Dual Rectifier has become the amp of choice for a long list of chart topping devotees outside the world of heavy.

MULTI-WATT POWER AND OUR FAMOUS 5-BAND GRAPHIC EQ
Running 2x6L6 octal-base pentodes, and features the 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.

 

RICH ALL-TUBE REVERB ENHANCES THE SPATIAL QUALITY OF YOUR EXPRESS PLUS
The 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.
