The Nemesis amps still achieved the same clarity of sound that their much more expensive World Tour series did but, lacking the tube or the Golden Ear chip in the pre-amp circuitry, did not have the warmth of the World Tour series. The new Nemesis amps used a blue face instead of the well-known gold face of the WT series and were known as the NA series (Nemesis Amp) in both heads and combos. They were very articulate amplifiers and became popular with the "touch bass" crowd, which needed the articulation more than the warmth, as well as a lot of rock bands, which also didn't miss the warmth but needed the clarity.
