A Multi-faceted Boutique-style Tweed from Mesa

Inspired by the legendary Tweeds of yore, the Mesa/Boogie California Tweed 6V6 4:40 is a 6V6-loaded amp with Tweed-based performance. And it’s incredibly flexible — its Multi-Watt power amp features Duo-Class and Dyna-Watt technologies, yielding five power, two operating class, and three wiring options. Enjoy a stylistic choice of voicings, thanks to Normal and Low inputs that are easily shaped via a 3-band EQ and Gain, Presence, Reverb, and Master controls. Add incredible dimension to your playing with an all-tube, long-tank spring reverb. Got pedals? No problem — integrating them is a breeze, by virtue of a fully buffered, series tube effects loop. Want to enter boutique territory? Fire up the California Tweed 6V6 4:40, and you will.

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.

Built in the USA to rock hard — and reliably

Mesa/Boogie has been handbuilding some of the most sought-after guitar gear in Petaluma, California, since the late '60s. Early fans of Mesa/Boogie gear include Carlos Santana and Keith Richards, guitarists whose tones have been chased by countless musicians for years. When you plug into the California Tweed 6V6 4:40, you're tapping into decades of innovation. The guitarists at Sweetwater appreciate the top-notch sound and construction you get in the California Tweed 6V6 4:40.

It's hard to imagine a more quintessentially modern guitar amplifier than a Mesa/Boogie, and when Sweetwater guitarists want high-gain tone, Mesa is where they start. One thing we love about these amps is their sheer versatility, such as the massive range of tone you get from each channel, the freedom to use the tubes you love, onboard CabClone cabinet emulation, and MIDI control. And it's not just guitar amps - Mesa/Boogie's bass amps and pedals are equally cool. What's more, thanks to our incredibly close relationship with Mesa, you can even customize your own amp right here on Sweetwater's website! Get the sound and style you want from your next amp, with a Mesa/Boogie from Sweetwater.
