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.

I've been fortunate to have been playing Mesa since 1998 from the Tremoverb to the Road King and this amp is easily a classic. If you want that blackface tone it's got it, if you want the tweed sound it's of course there too along with everything in between. The build quality is as expected with Mesa, unparalleled. The baby blue is a show stopper. The combo is fantastic in that the bass never farts out ie Fender. It's basically everything you want your Fender to be and more. This thing is a nostalgia machine and takes pedals exceptionally well too. Could not be happier and Nick always makes it so easy to spend money at Sweetwater. Shipped as if it were a relic complete with candy!

Amazing Amp, Great Service

I'm feeling like this is my forever amp, I'm able to dial in the tones I want and find lots of variation in the settings. Kenny helped me make the decision and sat through me toiling about getting a great amp or a digital setup, so thank you Kenny!

They Don’t Call It Boogie for Nothing!

From airy, shimmering cleans to raucous crunch and everything in between, this is a truly great amp. I love it.
Rated 5/5

Tone.

What a beautiful amp! Side by side with my 65 Blackface Reverb there are similarities - the DR is def brighter + farts out easier on strumming. The CT can take aggressive strumming while maintaining structure much better than the DR. I'm sure if I jacked up the presence I could find shrill highs, but why do that to yourself? The multi watt is helpful if you want to get into fat tweed breakup at reasonable volumes - although I honestly don't think that's why anyone buys this amp. This is a clean machine. To be overly simple I would say Blackface Deluxe Reverb with a mid knob, presence, gain/volume, fx loop + birch cab. Takes modulation pedals extremely well.

As far as Sweetwater is concerned - same as always. Great service, fast shipping and delivery even during tough times. Can't recommend enough. Thankful they can get these in stock with all the shortages. As usual my daughters are arguing who gets the amp when I'm too old to use it while they eat the courtesy bit o honey's :)

Wow!

Been playing bar gigs for 25+ years and have had several different amps over the years. I recently sold my twin reverb to buy this amp and although I will miss the Fender, I wont miss the weight and the tome from the California Tweed is unreal. I have played a handful of shows with it this summer, each different size rooms and a couple of outdoor shows and get the amp to break up and just the right volume in any setting using the attenuator, and I get comments on the looks from people who dont even play. LOVE this amp!

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.
