Finally, the long-awaited successor to SWR’s beloved Basic Black is here! SWR’s new 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.
