Comments about Roland KC-550 - 180W Keyboard Amplifier/Submixer:
I use a Kurzweil 88 and a Yamaha Motif 7 keyboards stacked on stage and needed a powerful and warm sounding amp to cover the variety of frequencies from the two boards. The KC-550 did it all. The ability to to run in stereo created the environment on stage and out front that opens the sound for other musicians on stage to play and pleasing to the public ear out front. I highly recommend this amp to any professional keyboard player who is looking for the ultimate sound experience.

Comments about Roland KC-550 - 180W Keyboard Amplifier/Submixer:
Actually I already owned a KC550 and I bought this unit for a friend. He was so impressed with my unit that he wanted one just like it. We both use this for our Roland drum sets but you can plug anything in and it sounds great. Don't believe a guitar doesn't sound right on a keyboard amp. You can gig a small room with this unit-no problem. The only negative is a little heavy but if you want that deep bass you gotta pay the price.

Comments about Roland KC-550 - 180W Keyboard Amplifier/Submixer:
Plenty of power for stage monitoring with the rock guitarist blazing. I like the input mixer, but a variable gain stage on the line input would have been nice.
I've been using Roland product for 30 years and it did not disappoint.
