Reinhold's LaGrange pedal is designed to emulate the famous "plexi" amplifier sounds, which every legendary guitarist has played at one time or another. The LaGrange has a wide variety of sound shaping tools, including switches for gain, variac, presence and structure. Knobs include volume, gain, tone, and a channel mix that simulates the two channels of a 4-input Plexi 67-69 amplifier. Unlike the Ecstasy Red and Blue pedals, the Grange offers independent boost with adjustment of level and an expression pedal input that allows you to connect the output of a volume pedal to control the gain of the LaGrange.
