I Purchased a Motiff ES7 and already owning 1 KC550, 1KC500 & 1KC100, I wanted to try something new. I saw the Sumo and almost lost my mind I was so impressed. I shorty became disappointed after using it for an hour or so. I compared it to the KC550 and theres no way I could ever use this amp live. I would be laughed off da block. The Sumo's only for show of strength and not the real deal. Stick with the Roland line. YOU'VE BEEN WARNED.
The Alesis Sumo 300 appears to pack some punch at 300 watts. However, don't let wattage deceive you. Volume per watt is all about the efficiency of the amplifiers technology, and quite frankly, the Sumo 300 is not very efficient. While the sound remains clear and distortion free when pushed to the limit, full volume is hardly what you'd expect from a 300 watt unit. I also found that with all 4 inputs pushed to or close to full power, the Sumo would simply shut off. Power cycling it doesn't fix this, you simply have to wait a few minutes for power to be restored. Thankfully this never occurred live. The effects are mediocre, and it's important to remember that everything comes at a cost, and you get what you pay for. The more extras you get for the same price, the lower the quality of what you're actually look for, and that's the amp.
i see a lot of negative critism, but i think that's because many seem to be looking for raw volume out of an amp designed for quality sound, this amp was not designed to be a stand alone on a gig. mic it to the PA at about 50% and it's fantastic! for what it's designed for, and it's intended prpose, it's hard to beat.
But the sound quality was very poor. I'm really disappointed - now I have to go through a bunch of paperwork to get this returned, and postpone a gig, and .. oh man. "Too perfect to be true", I guess. If you know how to replace a speaker or touch up an amp, you could go inside this thing and fix it cause everything else is amazing. Just a little disappointed in quality.
