Master Effects Golden Ratio for sale in mint condition. This is a spot-on clone of a vintage 1970s Electro Harmonix Clone Theory, complete with the coveted MN3007 bucket-brigade device (BBD) chip, but without any of the issues of the vintage units due to a number of modern adjustments. This is a must for Peter Hook fans! The pedal nails those Joy Division and New Order bass tones perfectly.
