Iron Ether Subterranea synth, awesome pedal. Bought it form a fellow TB'er. Love the pedal, just not using synth sounds now. Paypal only, shipping included to the lower 48. The Subterranea is a multi-timbral analog synthesizer and octave pedal, designed in collaboration with engineer Don Stavely. It offers three synthesized voices that track the input pitch – two with selectable waveforms and a third with a unique sound and its own lowpass filter. All voices can be mixed together with the original sound to create a massive synthesized voice which can be used as the “master oscillator” for a synth effects chain.
