Customer Reviews
4 out of 5 (34 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Alesis Langiappe, a little extra"
Sound: Clear, clean, balanced, neutral, sound. The dsp stereo is a surprise. The effects sound good, but I have not had occasion to need them yet. Some demerits because I think the amp should be louder. Its 100 watts do not seem to be as loud as my kbr-m's 100 watts at keyboard input, but turning it up does not degenerate the sound in the least. It's probably just the difference in the cabinets and a little + & - applied between manufacturers. No big deal. No extraneous noise. Feature: Stereo dsp lets you hook right and left synth outputs into the sumo and hook amp #2 with a stereo out jack from the sumo to amp #2. Good expanded stereo effect. I used it with a roland kc100, and with a motion sound kbr-m successfully. The effects - 8 reverb, 2 chorus, flange, rotary, delay are cool - work through the dsp. 3 band eq. mc input. I like the handle and wheels - easy to tote around Quality: It is well made. Value: I got this for $249.00, a price match from $299.00, which I think is a good deal. This amp is a bargain - good value. Manufacturer Support: Have not had the pleasure of needing support, but I assume that Alesis stands behind its gear. The Wow Factor: Well, I must have wanted it, I bought it! Not a lot of sex-appeal, except for the blue-lit 'Alesis' logo when it's turned on. It is a practical addition to my rig. I initially was going to get a Motion Sound km-12 [100 watts] to set up piano/rhodes in stereo with my kbr-m. I just could not make myself spend $500+ on it. I wanted a budget amp. So I auditioned this one at GC and a-b'd it with a Behringer kx1200 at the store. The sound was equivalent, and the Alesis won on looks, size and portability. Then when I figured out what dsp was and how well the stereo worked it turned out really well. Overall: I am out of the amp business for the time being. I would buy another one.

"Finally, a decent keyboard amp!"
Sound: I've always hated keyboard amps, but this thing is winning me over. When I first plugged it in (in my studio) I thought it sounded terribly weak, with a strange bump in the upper mids. This is probably because I was sitting with my ears at the same level as the horn (hi freq driver). Then, when I took it to church and set it up on the platform and moved a few feet away, I couldn't believe that it was the same amp. It really does sound pretty darned good. Most keyboardist want to hear the sound of their favorite studio monitors, even when playing live. The sumo sounds instead like a small PA. It certainly sounds better than the monitor wedge I had to use before! I'm glad I bought it. Feature: The inputs were what sold me on the Sumo, as opposed to buying a powered mackie speaker. It has 2 XLR outputs to send to the main PA, so your keys are sent stereo, even though you are hearing mono in the Sumo itself. The handle and wheels are great. I like the blue glowing logo. Ease of Use: It certainly is easy to use. Quality: Seems well built. Could have more substantial knobs, but then again I only paid $250 for it. Value: It's only $250, and you can use it as a mini PA. Sounds good. A simple powered speaker will cost you $350, and it will only have 1 input. I feel like I got more than I paid for. Manufacturer Support: Alesis is usually OK with support. The Wow Factor: The blue logo. What can I say- I like it. Overall: The Sumo 100 works for me. It gives me control over my own sound, as opposed to having to depend on a monitor wedge (and a shared monitor mix). It sounds good enough for me to aim it out to the audience, and feel that they are hearing my sound the way I want them to.
