"This little analog synth is known for its amazing bass sounds. What makes this Rogue a great buy is that it's been cleaned internally and the foam layer has been removed. All Moog Rogues (and Opus3s) had a layer of foam to separate the faceplate and the circuit board. This synth has been de-foamed and cleaned to prevent foam from causing any damage.
Has CV and S-TRIG/GATE connectors to be controlled externally. You could use a MIDI to CV converter to control via MIDI (Kenton Pro Solo would work nicely)."
