MESA's proprietary Dyna-Watt™, Class A/B Power Amp with a single, global Full/Half/Low Power Switch. Each setting features a different tube count and/or wiring configurations. Full Power Mode utilizes all 4 power tubes, producing 98 (clean)/112 (max). Half Power utilizes 2 power tubes, producing 40 (clean)/50 (max) Watts. Both Full and Half Power Modes operate in Class A/B Pentode for maximum power, punch and clarity. Low Power Mode utilizes 2 tubes operating in Class A/B Triode for lush harmonics and a sweet, liquid feel at lower volumes, producing 22 (clean)/30 (max) Watts.
