The Electro Harmonix Superego Synth Engine Pedal is a guitar effect of the type that could only come from EHX. It takes the technology from it's own 'Freeze' pedal, but adds new, creative and inspirational features. The 'freeze' holds the guitar notes played giving them 'infinite sustain', lending the tone an ambient, otherworldly feel. Notes can also be layered, such that a note can be frozen, and other notes played and sustained over the top.
Unlike the original Freeze pedal, the Superego has a new Gliss control. This acts as like a portamento effect, such that one played note 'slides' in pitch, into the next note. The Gliss control adjusts the time it takes for one note to reach the other.
Another unique feature of the Superego is the effects loop. This allows the frozen output to be routed through additional effects, and mixed with the original signal. The pedal can be operated in Latch mode, where notes are frozen by momentarily pressing the pedal switch down, and auto mode, which sustains notes automatically.
