With the Roland KC-60 Keyboard Amplifier, you get a whole lot of flexibility for your dollar in this scaled-down model that retains that sought-after KC sound. The amp's 40W power section drives a 10" speaker through 3 separate channels that include 1/4" line, XLR mic, and aux inputs so you can easily add vocals and backing from other sources. Rotary controls adjust channel and headphone outputs plus low and hi EQ. Also, the Roland KC-60 subwoofer output offers big bottom-end potential.
