In 2010, the Nemesis line morphed one final time. Under ownership of USM after the founder had departed, the decision was made to pull the Nemesis EN amplifiers into the newer Black-Faced WTB series. At the time the only other WTB amp was the WTB1000, which was basically a WT800 with selectable 8-band graphic EQ and one semi-parabolic control. The only similarity between the WTB1000 and the WTB400 and WTB700 was the single semi-parabolic control that could be turned on or off. Otherwise they were entirely different pre-amp and power sections.
