Built-in subharmonic synthesizer.

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.

"Sound Fantastic....Quality questionable !"

Overall: 4 out of 5 stars
(see rating details)
Sound
What can I say, probably one of the best amps I have ever used and thats 35 years in the business. Sound quality and control cannot be faulted. Quality is questionable, no doubt it is bullet proof build quality but the on/off switch seems a little fragile and on mine there is a very sharp edge to the grate covering the heat sink on the back. Small things I know but cut your finger on the way to a gig and youre in trouble!! Weight is perhaps another problem unless youre built like a gorilla !
