Releasing Bypass again fades out the held sounds. With both the Moment and Auto LEDs lit, the Superego+ automatically freezes and holds notes as you play as long as Bypass is held down, with the Threshold knob setting the triggering sensitivity. This way you can freeze a sound and then play over it using the dry and wet signal controls to set the balance. When you release the Bypass switch, the frozen signal fades out according the Decay setting. In Moment mode, the Superego+ freezes whatever is playing as soon as you press and hold down the Bypass footswitch.

How the Freeze part of the pedal responds depends on what’s displayed by the Mode foot switch status LEDs as you step through the options. Like the original Superego pedal, the sustain/synth part of the Superego+ has its roots in the EHX Freeze pedal, with which pressing a switch could provide infinite sustain by freezing the sound. The effects are applied to the synth signal other than in Live Effects mode, where they affect the entire input and the synth section is bypassed.
Superego plus plus#
There are four foot-switchable Freeze modes: Moment, Sustain, Auto and Latch, plus the Live Effects mode. The black knobs to the left address Dry level, Effect level, Attack, Decay, Threshold, Layer and Gliss. Note that the filter stays where you set it unless a pedal is connected - there’s no filter envelope facility included.Īdding an optional expression pedal allows for pitch glides, rotary speed change, wah or multi-parameter morphs you can store (for each effect) one set of up to seven parameters for the fully up position of the pedal and another for the fully down position, and moving the pedal morphs between them. Most of the effects, which are all digital, are based on the sound of existing EHX products, so you pretty much know what to expect. For those effects for which rate and depth are not applicable, the two knobs access different parameters, as denoted in purple and green text below the effect names.

The effects section, which has its own bypass switch, has controls for Rate and Depth, and an 11-position switch selects between Detune, Delay, Echo, Flange, Phase, Mod, Rotary, Trem 1 (sine), Trem 2 (Square), Pitch (☑ octave in steps) and a resonant Filter. The Superego+ has a buffered bypass, and a 9.6V DC adaptor is included. By default, the wet and dry signals share the same output but if you want to split them, the effects loop send can carry the synth-only signal, leaving the main output to carry only the dry signal. Other than the power inlet, there are six jacks, two for in and out, two for a send/return loop and two TRS jacks for the external controllers.
Superego plus how to#
A TRS expression input allows for real-time effect parameter control using an expression pedal or 5V CV signal, and there’s a further TRS jack socket for an optional three-switch controller the manual even shows you how to make your own if you are handy with a soldering iron! While the pedal can be used in stand-alone mode, the additional controller options open up a lot of additional possibilities, and I’d recommend at least hooking up an expression pedal. The latter allows notes to be held indefinitely, have their envelopes modified and have glissando applied for pitch glides. There are really two parts to the Superego+, the multi-effects section on the right and the sustain/synth section on the left. Unlike the same company’s Synth-9 pedal, it doesn’t set out to emulate existing synth sounds but carves its own niche, although having said that, it can serve up a fairly convincing emulation of a Roland GR-300! Overview And because it processes the guitar signal itself, it doesn’t suffer from any of the usual side-effects suffered by pitch-tracking guitar synths. The Electro-Harmonix (from hereon EHX) Superego+ is a sort of guitar synth, though not in the traditional hex-pickup sense of the term: by means of some seriously clever processing, it can create a range of polyphonic synth-like effects with nothing more than a conventional guitar signal as its source. Pairing EHX’s impressive ‘freeze’ technology with a multi-effects processor opens up a world of creative possibilities.
