This amp feels like a more professional purchase. You connect your noisemakers in the back, not the front. The slim front panel is for 15 knobs, controlling everything from FX to volume (both on all four channels) to three-band EQ (master). The Alesis logo glows blue when powered, which is a nice addition (I love lights!) The sound itself is GREAT, crisp and clear just as they say. Gotta love wheels and a cool little carry bar thingy... I have no idea what 300 watts is supposed to sound like, but I can imagine this is pretty close! Now the only problem is that everyone in the club will hear you if you screw up! -Oh, and help your delivery guy unload this when it comes... *If this was to burn up soon, I would box it up, pay for shipping, and get a new one; all with a smile.

Some of the Alesis speaker products are just way below the standards even for amateurs.I made a mistake of buying years ago small home studio monitors (point 7) which really should be used as rear speakers for home theater surround systems.?Sumo? belongs to the same family of products which hopes to be sold since customer trusts the brand name. It is a heavy amplifier that bass sounds boomy with annoying piercing high and midrange adjustment. The idle noise from the inputs is high and easy to hear in quiet rooms. The CD player hooked up for testing will make your ears fatigue quickly no matter how you tweak the EQ. It seems to be just a bad design of crossovers and probably cheap speakers. It looks cheap as well with silver knobs and hard to read labels. ?Cool? blue Alesis backlit sign does not help. I don?t believe hooking up another system for a stereo effect is going to help but rather amplify the harmonic distortions. I am looking currently at Yorkville and Unico products which receive lots of good customer reviews and returning ?Sumo? back to the store.

For the price its ok

By FaTM1Ke

from Virginia

You get a lot for the price but don't let your high hopes fool you, this doesn't perform as the specs might suggest.Pros: Decent sound quality, good bass response. Usable effects, many inputs/outputs. Solid build quality.Cons: In order to be used in a band setting the amp needs to be cranked at near max output, 8 or so on master and input volume controls. When treble is turned past 7 at a high volume there will be a noticeable hiss coming from the horn when not being played through.

Not what I expected in a bad way

By bandman 71

from Ohio

In short this amp was a great idea that never got fulfilled. The features are nice, but the performance is way below standard for the brand name and from the product description. I don't know who rated this amp at 300 watts, but it sounds like 75. Very disappointed and I sent it back after trying it out once. Low power and poor audio reproduction.

sorry bout their luck!

By sound mountain productions

from upstate new york

our group owns two of these, wired in stereo with the link feature as intended, to power an sp-88 kurzweil and an alesis quadrasynth. they're a breeze to move, (no wheel issues at all on either of ours), and sound awesome; very natural or with the room effects. the power rating is probably 150rms, enough to nicely drive the good sized cabs. we use the external lo-z outs to our ssw-15a nady powered stereo sub, which feeds 2 way kustom 15's on poles; awesome result! in a nutshell, you could spend (a lot) more and still not come out with a rig that would beat 2 of these linked together. true stereo!

It pains me to write this...

By Uncle Funky

from Savage, MN

I have plenty of Alesis gear and that's why I bought this amp.It's cheap down to the plastic knobs. It was a total bust for us as a band. Not nearly enough volume for anything! For an amp this weak it's way to big. The cabinet is cheap. The sound is cheap. The handle is cheap and bent right away. The wheels are cheap and way too small.The amp was a good idea and Alesis should double the price and make it right.The Alesis logo does light up and that kinda cool.

nice pa amp

By rob-8Npjv

from Flint, MI

i use this amp for PA settings and this amp works very well, i noticed that it doesnt work well with keyboards tho it has aloud hissing sound and isnt very loud at all, other things that i do with this amp is i hook it up to my marshall valvestate vs232 and this amp really makes the sound come out! i would rec. this amp to players that want a simple pa system but i wouldent rec. it for keyboards.

Big look Small sound

By Joseph Blount

from Statesboro Ga

The Alesis Sumo 300 Keyboard Amplifier is more like a pratice amp.Not for a gig just for a one mans show.The Tweeter went out in a few weekson me.And about the 300watts more like 300x4 at 75watts per channel.And it makes a cracking sound with the knobs sounds like loose wire. The Sumo would be excellent for a not so lound setting.

crackle crackle

By bipolarart

from Upland, IN

All I've ever used it with is an Alesis Micron, blew the horn in no time. Now I have a steady crackle when I play. For some songs I like the crackle... gives it an old-school feel, but that's beside the point. I guess I just pushed it too much, but its 300W should get louder than it does. Get a good bass amp and run your synth/keyboard though that. I used my bassist's Crate full stack the other day and it sounded great. My friend used to run his microKorg and MS2000B though an Ampeg 8x10... that shounded amazing.

Looks Good!

By Mark-s6wxv

from Midwest

Cabinet is solid! and the amp is constructed very sweetly inside, they did a good job. But the speakers are almost a joke. My 12" opened up almost immediately and the horn I would call fair. I get noise (pot noise) from the effects knob like the darn thing is 20 years old or something.

Just Say No to Sumo

By keyman21-xAmfh

from Loves aprk,il

Bought a Sumo 300 about 2 months ago. Totally disappointed. This thing has no power to it. I can barely hear myself on the stage when the other band members are playing. The overall sound has no depth to it. Extremely tinny sound.I was going to use my roland 550 as a practice amp and use this one on stage....bad idea. I will be returning this amp as a trade in asap
