The New Scrambler Series Pedals are based on the original cosmetic design of the Ampeg Scrambler pedal from 1969. The SCP-OD is the reissue of the Original Scrambler. It features a distortion circuit that adds upper octave harmonic content, while blending a unique overdrive effect to the signal. These pedals feature die-cast housings and True Bypass circuitry. A Scrambler is not for smooth blues or the faint of heart - it's a NASTY sounding fuzz but you can tame them a little if needed.
