1971 Maestro Ring Modulator

Here is a vintage 1971 Maestro Ring Modulator RM-1A guitar effects pedal with original matching expression 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.

For those who searched for this specific ring mod and came upon this listing, you are probably 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 original matching Expression pedal makes this unit much more tactile, interactive, and eloquent. Both pieces are in extremely excellent, new mint, condition.

The pedal works perfectly: all sliders are smooth and functional and the slider caps are original. The pedal is the finest example I have seen available, and couldn’t be nicer short of including an original box.
