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-990 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-990 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-990 keyboard amp features a custom-designed 12″ speaker for exceptional fidelity. Combined with its built-in tweeter, the KC-990 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-990 amplifies it with stellar sound quality.
