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.

"Hey, check this out."
Sound: The sound is not bad. I play at a piano bar and set up my keyboard next to a piano. I use the amp to amp my keyboard and also use the mic input for singing. In this type of setting it does great! When I play in a band, there is no way that it would keep up with the PA but for its size it does just fine. Ease of Use: Theres not much to it, plug it in and turn it on. Basic controls make it very easy to use. Quality: I have had mine for about a year and a half, I have played 100+ gigs on it and taken to little jam sessions (lots of drinking) and this little speaker has taken more than its fair share of abuse and works just like it did the day I brought it home. 3 months ago I forgot to strap it down in the back of my truck and it went rolling around over my keyboard stands and I thought that was it, There was one little blemish on the vinyl covering, I thought there would be more damage and wondered if it would work, but so far so good, it has not let me down. Value: I think its worth the price, especially for how much abuse it will take. Manufacturer Support: Never have dealt with them, no need so far! The Wow Factor: Its size and ability make it appealing and very easy to transport and use. Overall: When this one wears out, I'll probably get another one. Its been great for my weekly gig.
