Building on the synthesis platform of the award-winning Superego, our new Superego+ raises the bar when it comes to creating synth effects, sound layers, glissandos, infinite sustain and more. Plus, we’ve added a complete effects section featuring 11 effects types, an EXP input for effect parameter control and an EXT jack for a 3-button controller.


The Superego+ is equipped with the following effects:

DETUNE: pitch detune, EXP pedal controls pitch

DELAY: warm, analog sounding delay, feedback is preset, EXP controls delay time up to 2 seconds

ECHO: pristine digital delay, feedback is preset, EXP pedal controls delay time up to 2 seconds

FLANGE: Electric Mistress style w/filter matrix, rate and feedback. EXP pedal controls rate

PHASE: Small Stone style phase shifting with rate and depth control. EXP controls rate

MOD: pitch-based vibrato or chorus. EXP controls rate

ROTARY: rotary speaker style sound. Depth controls tweeter/horn balance. EXP pedal controls rate

TREM 1: sine wave tremolo. EXP controls rate

TREM 2: square wave tremolo. EXP controls rate

PITCH: pitch shifting effect over a +/- one octave range. EXP controls whammy

FILTER: resonant low-pass filter. EXP pedal controls frequency


The pedal provides enough sound shaping control to please the most sonically adventurous player and is equipped with Dry, Effect, Attack, Decay, Threshold, Layer and Gliss knobs, plus Rate and Depth knobs for the Effects Section. Four foot-switchable Freeze modes: Moment, Sustain, Auto and Latch, plus a Live Effects mode where the dry signal is routed thru the built-in effects and the internal synth engine is disabled, are included.


The polyphonic Superego+ works with guitar as well as other instruments including bass, keyboards, vocals, drums, etc. and comes equipped with an EHX 9.6DC-200 AC Adaptor.
