A quick look at the control panel on the front of the California Tweed shows that this is a simply laid-out one-channel head. The channel features Normal and Low inputs, plus Gain, Treble, Mid, Bass, Presence, Reverb and Master controls.

In the late 1960s Randall Smith, one of the most celebrated amp technicians in the San Francisco Bay Area, was inspired to build his own amplifiers after coming to appreciate the tweed circuits of the 1950s. He loved their organic tone, the effective controls and the way the sound would smoothly move from clean to overdrive and back again when the gain control was used. Smith's first venture into boutique guitar amplification led to a new Mesa/Boogie amp design inspired by these wonderful, timeless-sounding amplifiers. Drawing on 50 years of experience, Mesa/Boogie now presents an exciting new world of tweed-based tone and authentic 6V6 character. A wonderfully simple design that raises the bar once more in the world of vintage tone: the new California Tweed series.
In the late 1960s Randall Smith, one of the most famous amp repairers in the San Francisco Bay Area, was inspired to build his own amplifiers after developing a fondness for the tweed circuits of the 1950s. He loved their organic sound, the effective controls and the way the tone gently moved from clean to distortion and back again when the gain control was used.
To push forward with his own amplifier designs and concepts, he settled in Pentaluma, California in 1969 and worked on further developing his amps.
The characteristic, heavily distorted sound of his Mesa/Boogie amplifiers was initially the result of an electrically mis‑dimensioned preamp. Founder Randall Smith wasn’t sure whether the preamp’s output would be enough to drive the power amp, and he built it with four twin triodes, of which the first seven triodes are still used today to amplify the input signal.
Many years later Mesa/Boogie has grown into one of the major global players in the market for high‑end guitar and bass amplifiers and is a leader in the development of modern amp designs and circuits. The American company also holds several patents on special features and circuits, such as Multi‑Watt™, Dyna‑Watt™ and the Mesa CabClone™ cab simulator, which you’ll certainly come across when browsing our selection of Mesa/Boogie products.
Of course, a maker of such innovative and high‑quality products has by now also gathered a large fanbase among professional musicians who got hooked on Mesa/Boogie amps. The best known users of Mesa/Boogie amps include the already mentioned Carlos Santana, Larry Carlton, Angus Young, Robben Ford, Eric Johnson, Keith Richards, Pete Townshend, Adam Jones, Mark Tremonti and Dave Grohl. Of course these aren’t the only famous Mesa/Boogie users, and Mesa/Boogie also boasts a large and steadily growing following among studio musicians and hobby guitarists. Maybe you’ll soon be part of the next generation of the Mesa/Boogie fan community?
