Mesa has continued to introduce new models in the 2000s and 2010s, with models such as the Road King II, the Lone Star and Lone Star Special, the Stiletto and Express lines along with lower watt versions of its large amps, such as the mini Rectifier, and the Mark V:25 and Mark V:35.
Introduced in the Mark II-B was the Simul-Class power amplifier stage, which combined tubes running in class A and class AB through the same output transformer.
