Awesome new features get you even closer to tube amp Nirvana

How do you improve on near-perfection? Well, that's always been the name of the game at Mesa/Boogie, hasn't it? Mesa's taken their Express 5:50, and injected even more perfection. The Express 5:50 Plus features an improved clean mode, with warm, breathing lows, increased sparkle in its highs, and tweaked S/N. You now get Mesa's full-blown Multi-Watt Channel Assignable Power with Duo-Class and Dyna-Watt technologies, letting you run your power tubes in any of three different wattage ratings (5/25/50) per channel - each having its own tone-bending wiring configuration and operating class! Mesa's legendary 5-band graphic EQ is now along for the ride - with additional controls that let you footswitch or auto-assign the EQ sliders or the preset control in each channel. Mesa's performance-juicing solo control is also onboard, giving you an additional footswitchable master output control that lets you preset your ideal amount of volume boost for solos and figures you wish to have additional emphasis - and trigger it on the fly. Lastly, a new 4-button footswitch gives you ready access to channels, reverb, EQ, and solo. Wow. Impressive updates - particularly for an amp many guitar players considered already perfect.

Great Boogie tube tones for all kinds of players

Wouldn't it be great to be able to use the same amazing-sounding amp for stadium gigs, club dates, and in the studio? Thanks to Mesa/Boogie, you can! The Express 5:50 Plus combo features three completely different power configurations, spread across two fully independent channels. Are you a tonal traditionalist? Select clean and blues for your two footswitchable sounds. If you're addicted to gain, choose crunch and burn. Then stand back as the mild-mannered Dr. Jeckyll morphs into the maniacal hardcore beast, Mr. Hyde. Most important is the classic authenticity of all these iconic tones. No matter what your stylistic destination, the express will get you there - fast!

Choose your power section

Up front, the 5-watt setting indicates the low power, single-ended magic of pure Class A. The 25-watt setting gives you medium Class A push-pull output that's ideal for club work. Got an arena gig? Move serious air with the Express 5:50 Plus's 50-watt Class A/B setting. This impressive tonal and volume flexibility is made possible by Mesa/Boogie's Duo-Class and Dyna-Watt technologies that deliver multiple wattages and both single-ended and push-pull configurations in the same amplifier. Very cool.

Mesa/Boogie's high-gain heritage

Mesa/Boogie founder Randall Smith started out modding amps for Bay Area bands in the late 1960s. His clients? The heavies of the San Francisco scene - the Grateful Dead, Jefferson Airplane, Quicksilver, Big Brother, Santana, Steve Miller, Country Joe and the Fish, and many more. Randall's famous hot-rodded Fender Princetons from this era are the stuff of legend: how could a little 15-watt combo get so LOUD? Ever since Randall handbuilt the first Mark I amps in a Northern California mountain shack in in 1971, the name Mesa/Boogie has been a standard-setter in high-gain guitar amplification. Today, guitar greats such as Carlos Santana, Al Di Meola, John Petrucci, Andy Timmons, and Kirk Hammett use the distinctive, versatile voice of Boogie amplifiers to forge their signature sounds. And you can, too.

Best Choice I've Ever Made

I was looking for a more versatile gigging amp since my Twin Reverb didn't give me too many options for anything past great clean sounds. I was originally going to buy a Mesa Lonestar, but thought twice considering that I couldn't get a whole lot of gain out of it. I loved the clean of the Lonestar but it wouldn't solve my versatility problem whatsoever, so I decided to give the Express 5:50+ a go. I've had the amp for a few months now, and I am so happy I made this decision. The clean channel is simply amazing. I have tried to use the Mesa and the Twin side by side, but I just can't go back. There is a clarity to the clean channel that is really striking. The lows can cut through while the highs are still singing. It has a ton of headroom, even though it doesn't have the wattage of the Twin. It basically blows the Twin out of the water. The blues channel offers a bit more grit and urgency and I use it nearly as much as the clean. Both gain channels are amazing, and with the preset scoop settings on the EQ, you can go from that awesome high gain Marshall sound to the more chuggy Double Rectifier scooped mids by stepping once on your foot switch. I am not even close to having fully explored everything I can do with this amp. The icing on the cake is the different wattage selections, which can drastically alter your sound without even having to re-EQ everything. The five band EQ is also something I always loved in Mesa amps, and I use it far more than I initially thought I would. This amp is a no-brainer. The number of options is amazing, but the quality of each of those options is pretty stunning. 10/10

Mesa Boogie Express 5:50 Plus Combo

I own several Amps from Carvin to Peavey and to Marshall. But something is always lacking. Boogie delivered it. I recently acquired a Roadster and now the Express and both blew my mind. Simply telling you my experience here with these two amps is not enough. So go to a local luthier shop try any Boogie and I can guarantee a wow from your face ;-)

Tone King

The Mesa 5:50 EXP is perfect for my needs. It's a studio amp and gig amp all-in-one and the tone is so pure. Portable yet "big" enough to fill a large venue and accepts pedals well but has some great fx right out of the box. Looks good. Sounds great. Very satisfied with the Mesa.

Excellent Amp

This amp is perfect if you want Fender and Marshall sounds in the same amp. Because the crunch is on channel one, I use the blues mode on channel two as my clean. I set channel two so it sounds like a clean tweed amp with the contour off and it sounds more like a blackface amp with the contour on. I don't care for the 5 watt mode, but the volume controls in 50 watt mode are good enough that I can play quietly with the 50 watts switched on. Overall, this is hands-down the best amp I've ever owned.

Great Amp

I have owned the two twelve version of this amp for six months. Like most Mesa amps it's a good idea to play around with the tone settings especially in unexpected ways. My current set up is channel one on Crunch and channel two on Blues but with the gain set low for a clean sound. Channel one seems to have a fatter bottom which fills out the overdrive nicely but seems boomy on clean especially when playing with a bass. Channel two has a very different tone. When set to clean (blues) I find it sounds great but not to boomy. Then there is the Contour control. There's a lot of tonal variation on this beautiful amp and I couldn't recommend it more. It's surprising how often I can use it in the 5 watt mode. Fifty watts is plenty just about anywhere. Best for blues and classic rock. Mesa makes plenty of other amps for metal.
