The B-52 LS-100 represents the latest in the ever expanding line of highly acclaimed B-52 guitar amps. New, user-friendly features combined with the latest advancements in preamp technology makes the LS-100 an outstanding choice for the professional player and the weekend warrior. The clean channel now has the innovative B-52 “Mid Cut” feature. This pushbutton allows you to select the classic, warm vintage sound or a pristine, almost acoustic-like tone with tons of headroom. The overdrive channels go from moderate classic breakup to monstrous gain, totally controllable thanks to the individual gain and master controls for each overdrive mode. The overdrive channels now feature the new, B-52 assignable Contour control. This allows you to preset the Contour control and have it automatically activate on the gain channel of your choice. You can set one overdrive channel for a punchy midrange tone with the Contour off and turn the Contour on the other overdrive channel for a massive, totally scooped out metal tone.
