Mesa Boogie California Tweed 6V6 4:40 1×12″ Combo, Cream Bronco Mesa Boogie

Introducing the Mesa Boogie California Tweed 4:40 6v6 1×12″ Combo Amplifier

A homage to Randall Smith’s boutique amplification legacy and the Tweed circuits of the ’50s, the Mesa Boogie California Tweed 4:40 6V6 delivers timeless tone and performance in an elegantly simplistic package. Bridging five decades of experience and innovation, this amplifier offers a refreshing dip into the golden era of sound, accentuated by 21st-century ingenuity.

Tech Specs

Furnished with 5x12AX7 and 1x12AT7 preamp tubes, the California Tweed is energized by four 6V6 power tubes. Its streamlined front panel features Normal & Low Inputs, as well as Gain, Treble, Mid, Bass, Presence, Reverb, and Master Controls. Further enhancing the amp’s tonal palette is a fully buffered, tube-driven series FX loop, and an all-tube, long-tank, spring reverb, adding dimension and texture to your sonic landscape.

At the heart of the amplifier is Mesa’s patented Incremental Multi-Watt™ Power Amp. Employing Duo-Class™ and Dyna-Watt™ technologies, it offers five power levels, two operating-classes, and three wiring options, all accessible through a single 5-Way Rotary Switch. Power options range from 2 to 40 watts, offering a myriad of tonal possibilities suitable for a wide array of musical scenarios.

The amplifier is crafted into a 1×12 combo format, weighing 46.4 lbs., and measuring 19 1/4″ H x 22 3/4″ W x 10 3/8″ D. The speaker chosen is an 8 Ohm Jensen Blackbird ALNICO 40, designed to faithfully reproduce the amplifier’s rich tones. A silicon diode rectifier ensures reliable power conversion, and an external switching jack is included for convenient reverb on/off switching.

In the Field

The California Tweed 4:40 6v6 is a versatile companion, fitting seamlessly into different playing contexts. From the home studio to the club stage, its wattage switch allows you to optimize headroom and breakup at different volume levels. Dialing to 2 watts can provide warm, vintage tones for intimate, low-volume sessions, while the 40-watt setting unleashes the amplifier’s full power for louder performances.

Moreover, its dual input design presents an easy way to alter your tone on-the-fly; the Normal input can transition from clean to overdrive, while the Low input provides a consistently clean tone. Whether you’re crafting luscious soundscapes in a studio or ripping roaring leads at a gig, the California Tweed 4:40 6v6 1×12″ combo amplifier brings the iconic golden California Tone to the forefront of modern music-making.
