MESA/Boogie King Snake Vintage Rock Gain

While many are aware of the signature Carlos Santana sustaining lead sound from the King Snake (and original Mark I amps), some may not be aware of the outstanding Vintage Rock Gain available from the King Snake. It was the circuit that changed gain forever in 1971 - All-Tube Preamp Cascading High Gain. Plugged into Input 1, Volume 1 cascades gain into Volume 2 and additional preamp tube stages for stunning, musical saturation for classic rock rhythm sounds or the signature sustain solo sound the Mark I & Carlos Santana made famous.
It was a revolutionary innovation in rock n' roll that set the stage for the way every all-tube high gain amplifier would be designed.
Signal Chain: King Snake 1x12 Combo and Fillmore KS-100 Speaker, through the Bridge Position Humbucker on a PRS Singlecut. Mic'd with a Sennheiser 421 (front) & SM-57 (rear).
