Mo , I too was looking for a compact, yet powerful keyboard amp with a strong bottom...I wanted something for my solo jobs..
I owned a couple of the smaller Roland keyboard amps KC series..They are ok, but don't compete with the older Roland Cube keyboard amps..{I still have a pair of Roland 100's(15")..plus another as a spare]...I prefer these over anything I have used..For punch and bottom...nothing beats the big bottom of the old Roland's..
I bought and sold the Alesis 100 and 300..Poor quality, and tried some of my older small amps too..About a year ago, after reading about the Traynor K4, and being a fan of Yorkville sound[Distributor]..I decided that was going to be the unit for me...Last December I followed through and purchased[without trying it]..and I liked what it had and it's features...Bass response was excellent[a 12" that competed with a lot of 15" units]..I was reluctant to use it on larger jobs [250 people or more]..using my Roland's instead[70 pounds each]..Then I did an indoor job [200 people]..it breezed...Than an outdoor gig with 300 people..still breezed..never ran more than half volume..
I even pushed the bass[EQ]...and dancers loved it...
The tubes add to warm up sounds that could use more warmth..
Try it before you pass on it..
