The SansAmp Classic is one of the most flexible and sophisticated amp modeling pedal on the market. You can obtain a wide spectrum of the industry's most sought-after tube amp sounds and customize entirely new ones as well. Still made almost entirely by hand,the Classic's main module contains a bank of eight Character switches, which adjust the fine and subtle nuances of tonality, harmonics and dynamics. Its unconventional design not only keeps the unit compact, it is the key to the wide range of sounds you can achieve. The 3-position input switch gives you a choice of pre-amp styles: LEAD for Marshall-type pre-amps with mid-range and highs emphasized. NORMAL for Mesa Boogie-type pre-amps. BASS for Fender-type pre-amps (excellent for rhythm guitar as well as bass). The knob controls shape pre-amp contours, power amp contours, volume and final tone. With SansAmp Classic, there are countless permutations for you to explore. Sample style settings include: Vintage (AC/DC) and Hot-Wired (Van Halen) Marshall; Mesa Boogie; Hiwatt; Fender Lead (B. B. King), Rhythm and Bass; and Ampeg SVT.
