This Moog Sub 37 Tribute Edition Synthesizer is a superb and highly portable analog synth that's controlled via digitally generated modulators and contour generators. Modeled on a three-octave, pressure-sensitive keyboard, it has a steel chassis and wooden sides that's loaded with a control panel that resembles a full-sized synth. It has dual oscillators similar to the Sub Phatty, only the Sub 37 allows you to use its oscillators independently with a duophonic mode. It features a selectable monophonic or paraphonic polyphony, 37 semi-weighted keys, and a small LCD screen that's easy to read. It also has 16 banks and 16 presets per bank (that's 256 presets!). That gives you an absolutely crazy amount of creative control in a synth that weighs just a little more than 20 lb. and is just over two feet wide. The Moog Sub 37 Tribute Edition Synthesizer is an immensely versatile monosynth that offers a ridiculous amount of control over whatever sound you want to create.
