Mesa/Boogie California Tweed 4:40 1 x 12-Inch Guitar Combo Amplifier

Beautifully Simplistic - The Mesa/Boogie California Tweed 4:40 1 x 12-Inch Guitar Combo Amplifier

In the twilight of the 1960s, SF Bay Area amp repairman to the Stars, Randall Smith, was inspired to start building his own amplifiers after coming to a deep appreciation for the '50s Tweed circuits. He loved their organic sounding voice, powerful controls and the way they smoothly transitioned from clean to clip and back again.

Standing on the shoulders of a giant, Smith's (and the World's) first venture into boutique guitar amplification resulted in a new Boogie amp design inspired by that wonderful, timeless sounding preamp. Five Decades later they return to pay homage. Now, drawing on these 50 years of experience, we bring forward an exciting new realm of tweed-based performance and authentic 6V6 character. A beautifully simplistic design that raises the bar in the world of vintage tone. The NEW CALIFORNIA TWEED.

A quick glance at the front panel of the California Tweed reveals single-channel simplicity. Channel features include Normal & Low Inputs, Gain, Treble, Mid, Bass, Presence, Reverb & Master Controls. Our legendary vintage all-tube, long-tank, spring reverb with external reverb switching jack and a fully buffered, tube-driven series FX loop round out a feature set that delivers everything you need for golden tone, and absolutely nothing more.

Single Channel, 5 Power Voices, One Simple Switch

The California Tweed is powered by 4x6V6 Power Tubes while the preamp features 5x12AX7 and 1x12AT7 preamp tubes. Our patented Incremental Multi-Watt™ (Patent 9,917,560) Power Amp, featuring Duo-Class (Patent 7,173,488) and Dyna-Watt™ technologies, provides five power levels, two operating-classes and three wiring options via a single 5-Way Rotary Switch! Choose from the following power options:

• 40 Watts - 4x6V6 Class A/B Pentode
• 30 Watts - 2x6V6 Class A/B Triode + 2x6V6 Class A/B Pentode
• 20 Watts - 2x6V6 Class A/B Pentode
• 10 Watts - 2x6V6 Class A/B Triode
• 2 Watts -1x6V6 Triode + 1x6V6 Pentode, Single-Ended Class A Parallel

Harken back, bounce on forward, while never sacrificing one drop of golden California Tone.
