From Mesa Boogie:

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 we 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.
