This review has been selected by our experts as particularly helpful. "BEST AMP IN IT'S CLASS!"

Sound: THIS IS A GREAT SOUNDING AMP FOR THE MONEY - I PREVIOUSLY OWNED WHAT I THOUGHT WERE DECENT QUALITY ROLAND AND BEHRINGER KEYBOARD AMPS, BUT WAS NOT REAL SATISFIED - I BOUGHT THEM ON 30 DAY TRIALS, GOT MY MONEY BACK, AND MY THIRD TRY WAS THE ALESIS SUMO 300 - SINCE THIS AMP COST b$100 LESS THAN THE EQUIVALENT ROLAND, I WAS NOT EXPECTING GREAT THINGS - TO MY DELIGHT, THE SOUND WAS A LOT BETTER THAN THE OTHER 2 PRODUCTS - I USE IT FOR MY KORG TRITON LE KEYBOARD - IT HAS GREAT TREBLE AND BASS - THE ROTARY SOUND EFFECT IS AWESOME - THE SPEAKERS DO NOT DISTORT AT HIGH VOLUMES MAINTAINING A HIGH QUALITY SOUND AT ALL VOLUMES - I PLAY IN A BLUES/ CLASSIC ROCK BAND AND IT REALLY SCREAMS! - VERY SATISFIED! Feature: DID NOT COME WITH ACCESSORIES, BUT HAS ALL THE FEATURES AND OPTIONS I WILL EVER NEED - THE MASTER VOLUME AND CHANNEL VOLUME CONTROLS ARE SENSITIVE AND HANDY - THE EFFECTS ARE RICH AND NOT TOO PRONOUNCED AS TO DRASTICALLY ALTER THE CORE QUALITY SOUND - SOME AMPS HAVE OPTIONS THAT YOU WONDER IF ANYONE WOULD EVER USE - THIS ONE HAS FUNCTIONAL CHOICES THAT GIVE ME THE SOUND I WANT AND NEED - SOMETIMES I PERFORM SOLO FOR SMALL PARTIES - THE MIC INPUT IN THE FIRST CHANNEL SOUNDS GREAT - THE QUALITY OF THE KEYBOARD SOUND DOES NOT DIMINISH WHEN THE MIC INPUT IS USED, MAKING THIS A NICE COMPACT UNIT FOR SOLO GIGS. Quality: THIS IS THE HEAVIEST OF THE THREE AMPS I'VE TRIED, BUT THAT WEIGHT SEEMS TO EQUAL BETTER QUALITY - I ASSUME THE SPEAKER CONFIGURATION AND GUTS ARE SOLID AND CONTRIBUTE TO THE WEIGHT - THE BUILT IN CASTORS MAKE THE WEIGHT A NON-ISSUE - EASY TO HANDLE AND TRANSPORT - THE FACTORY QUALITY CONTROL IS EXCELLENT - I HAVE HAD IT FOR A YEAR AND HAVE HAD "0" PROBLEMS - I FULLY TRUST IT - I TAKE IT ON THE ROAD ALL THE TIME - IT HAS BEEN BANGED AROUND A LOT, BUT THE SOLID CONSTRUCTION SEEMS UNPHASED BY THE ABUSE I GIVE IT - I ASSUME IT WILL LAST A LONG TIME Value: THIS AMP IS A STEAL FOR THE PRICE - THE ROLAND I TRIED THAT COST $100 MORE WAS NOT EVEN CLOSE TO THE QUALITY OF MY ALESIS. Manufacturer Support: I HAVE NOT DEALT WITH THE COMPANY AS I HAVE HAD NO PROBLEMS WITH THE UNIT - A FRIEND OF MINE IS AN AWESOME KEYBOARD PLAYER AND HAS OWNED AN ALESIS KEYBOARD FOR OVER 10 YEARS - HE REPORTS NEVER HAVING A PROBLEM WITH IT IN ALL THAT TIME - HE RECOMMENDED I TRY THIS COMPANY'S AMPS - BASED ON HIS EXPERIENCE I DON'T ANTICIPATE NEEDING ANY REPAIRS FOR A LONG TIME, IF EVER. The Wow Factor: THIS AMP LOOKS BEAUTIFUL ON STAGE - THE CHROME CONTROLS ON THE INTERFACE CONTRAST WELL WITH THE BLACK FRONT - I LOVE THE ALESIS INSIGNIA THAT LIGHTS UP IN A NEAR NEON BLUE ON THE FRONT OF THE AMP JUST BELOW THE CONTROLS WHEN THE POWER IS ON - GREAT LOOK AND FEEL Overall: I PLAY BLUES AND CLASSIC ROCK IN SMALL BARS, CLUBS AND FOR PRIVATE PARTIES - IT HAS ALL THE GUTS AND QUALITY SOUND THAT I'LL EVER NEED FOR THESE VENUES - I DON'T PLAN TO CHANGE MY PERFORMANCE SETTINGS AS I'M A ROCKIN' ROLL RELIC AT AGE 55 - I HAVE NO REASON TO CHANGE EQUIPMENT AS LONG AS THIS ONE IS STILL GOING - HAVING RESEARCHED EVERYTHING OUT THERE, THIS IS BY FAR THE BEST PRODUCT FOR THE MONEY!

zZounds has verified that this customer bought this product from us. "Big Bang for Small Buck!"

Feature: I love the built-in effects. The flange is especially useful for the rhythm section I create. Quality: I had to rate it low on this because only one of them worked out of the box. The repair guy I took it to showed me the wiring inside and there was no sauter at all. It was like they forgot to connect the leads to the speaker at the factory, or maybe they used so little sauter it just fell off in shipping. Value: Definitely worth the money for the sheer volume of sound you can crank out of these bad boys. The Wow Factor: Love the little blue Alesis logo in the front. Tr
