"The 1972 Maestro Ring Modulator RM-1A guitar effects pedal. Considered by many effects connoisseurs to be the best and most important ring mod ever made. It was perhaps the collaboration between Maestro, Bob Moog, Tom Oberheim and ARP that resulted in this incredible synth module-like guitar effect. The RM-1A sounds like musically oscillating metallic frequencies reminiscent of an old sci-fi music score. It tracks almost perfectly and is extremely versatile."
