This is a vintage 1973 Maestro Ring Modulator RM-1A guitar effects pedal. Considered by most effects pedal 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, which produces sounds unparalleled by any pedal made since. With an average used resale around $1,000.00, it is still highly undervalued, so I suggest you take advantage of this offer!
For those who searched for a ring mod and came upon this listing, you are familiar with sounds this unit makes. For those who accidentally stumbled across this advertisement, this ring mod sounds like musically oscillating metallic frequencies reminiscent of sci-fi score from the ’60s. It tracks almost perfectly and is extremely versatile.
The pedal works perfectly: all sliders are smooth and functional and the slider caps are original. Aside from typical oxidation across the top, the pedal is in otherwise fantastic condition with the original bottom pads still intact.
