MESA/Boogie Roadster 100-watt 2×12″ Combo Amplifier

This all-tube thoroughbred shares a class with only one other amplifier – and that position is held by its brother – the mighty Road King. In fact, the Roadster is a Road King without Progressive Linkage and other rear panel features that some players fear need a higher education to navigate. The Roadster now offers the plug-and-play minded guitarist a way to enjoy a myriad of footswitchable preamp choices without the power option anxiety.
