The Scrambler Series Pedals are based on the cosmetic design of the original Ampeg Scrambler pedals from 1969. Our SCP-OCT Bass Octave Pedal features the Octave Divider circuit used on the popular SVT-5PRO, duplicating the input signal one octave lower. This circuit tracks fast and holds the note, even at low volumes. The SCP-OCT is a great addition to your tone arsenal.
