SWR's Black Beauty combo amp features a custom SWR 15-inch bass driver and high-frequency horn tweeter in a 4-ohm speaker configuration -- driven by 350 watts RMS (450 watts using a 4-ohm extension speaker cabinet). In addition to dramatic, new chassis graphics (featuring the SWR badge in classic chrome), the Black Beauty has inherited a very popular effect from the SWR Mo' Bass soundstation -- the SWR SubWave -- producing clean, pure and accurate octave signals. A Subwave Footswitch with a hardwired 1/4" cable (for connection purposes) ships with the Black Beauty as an added bonus.
