Tweed-based performance and authentic 6V6 character

When people say Mesa/Boogie, they naturally think about high-gain amps. There’s a reason for that — the company is legendary in that department. That said, back in the 1960s, Mesa’s founder Randall Smith was originally inspired by ‘50s Tweed amps. He appreciated their organic-sounding voice, powerful controls, and smooth clean-to-clip transitioning. The California Tweed 6V6 4:40 pays homage to Randall’s original inspiration, delivering Tweed-based performance and authentic 6V6 character.
