Electro-Harmonix Superego Synth Engine Pedal
Like the Electro-Harmonix Freeze pedal on steroids, times 10.
The Superego lets you layer multiple frozen notes, select which notes to freeze, output the frozen notes to external effects and even automatically gliss between different notes.
The polyphonic SUPEREGO Synth Engine reinvents sample and hold, performs fluid glissandos and creates oscillator like, synthesizer effects. It can stack sounds or create infinite sustain, it even lets you tweak attack and decay, or use its effects loop to invent novel synth patches. Indulge your guilty pleasures!
