Reinhold designed the LaGrange pedal with a wide variety of tone shaping tools and to emulate the famous "plexus" amplifier tones. Guitarists love the tools which include switches for gain, variance, presence and structure. Knobs include volume, gain, tone and a channel blend which simulates the two channels of a 4 input 67-69 plexus amplifier. Unlike the Ecstasy red and blue pedals, the La Grange offers an independent boost with level adjust and an expression pedal input which lets you connect the output of a volume pedal to control the gain of the LaGrange.
