California is a preamp/effect pedal in the Sansamp Character series, which emulates the tones of historically significant tube amplifiers using only analog circuits. It simulates amplifiers from the MESA BOOGIE Mark series and Rectifier series. A notable feature is the CHARACTER control, which allows you to manipulate changes in frequency, attack, and drive. Turning it to the left produces a Santana-esque vintage sound, while turning it to the right yields a heavy rock high-gain sound. It's designed to reproduce the sounds of both the Mark series and the Rectifier series. I used this effect pedal when playing Santana's "Europa" with my band. It offers a different distortion sound compared to Marshall-style distortion. Thank you.
