Deeper bass and better sonic balance

Roland's KC series amplifiers have been some of the most popular keyboard amps at Sweetwater for over a decade. This KC-400 represents the latest generation of the KC series, featuring a redesigned power amp and power supply. These not only provide more stable operation than ever, but they also help the KC-400 serve up deeper bass and a wider sonic range overall.

Custom speakers for enhanced detail and depth

To take advantage of its revamped power section, the KC-400 keyboard amp features a custom-designed 12-inch speaker for exceptional fidelity. Combined with its built-in tweeter, the KC-400 delivers solid lows, prominent mids, and detailed highs. Synth bass patches thump with authority, while piano and organ sounds speak with clarity and detail. Whatever you plug into it, the KC-400 amplifies it with stellar sound quality.
