MESA/Boogie California Tweed™ 6V6 4:Forty Official Demo 06:48

The all-tube California Tweed™ 6V6 4:Forty combines the best of classic tweed and blackface circuits in a simple, single-channel, pedal-friendly format. Powered by four 6V6 power tubes, our patented Multi-Watt™ power amp provides wattage options to fit any application. From 40 watts of gig-able clean headroom with four 6V6s down to two watts with two 6V6s wired in Triode and Pentode/Single-Ended, the perfect power-to-clip ratio is just a switch. Stunning, all-tube reverb offers nuance or vintage depth and is also footswitchable while your favorite effects will integrate beautifully in the finely tuned input or the tube buffered FX Loop. All the essential features you need, none of the complexity you don’t, and delicious 6V6 Tone at any wattage. Available as a 1x12 combo or medium (23”) head, the California Tweed Series also welcomes two vintage-tuned, matching 1x12 & 2x12 extension cabinets that deliver the classic resonance of the Cali-Tweed voice.
