TC Electronic has revealed that the new pedal they teased last week is an octaver - the Sub 'N' Up Octaver. It features an octave-up and two sub-octave controls, and can be used either as polyphonic octaver or a monophonic one. Like other TC Electronic pedals, it's also TonePrint-enabled so you can create your own custom settings. The editor features modulation options like flanger, chorus and vibrato, which allows for organ-like sounds. More info is available at the official product page.
