Electro Harmonix Superego Synth Engine Guitar Effects Pedal - Infinite

In this review the Superego Synth Engine is judged as a creative effects pedal aimed at guitarists and experimental musicians who want to transform single notes and chords into evolving synth textures. The bottom line: it stands out for its ability to create sustained, oscillator-like sounds and fluid glissandos while offering hands-on control of attack and decay. Players seeking more than a typical modulation or chorus will appreciate the pedal's layering and latch features; those who want simple, predictable auto responses may notice the sensitivity can require adjustment.

Key Features

• Controllable glissando: Smooth pitch transitions let players create synthlike portamento and sweeping note movement for atmospheric leads and pads.
• Infinite sustain: The unit can sustain notes and chords as long as wanted, turning short passages into continuous textures or drones.
• Effects loop: You can insert external pedals into the wet signal to sculpt unique hybrid tones and novel synth patches.
• Latch and layer modes: Latch mode with a layer feature stacks sounds so players can build complex harmonies and evolving sounds without holding the strings.
• Attack and decay control: Tweakable envelopes let you shape how quickly sounds swell and fade, useful for percussive or pad-like results.

Who It's For

The Superego Synth Engine is best for guitarists, session players, and producers who want to expand their sonic palette with synthlike textures, sustained pads, and layered sounds. It suits experimental players who enjoy sound design and chaining effects via an effects loop to craft distinctive tones.

It is less ideal for players who need a straightforward stompbox with highly predictable auto-sensing in every context; some customers report the sensitivity and auto mode behavior can feel unnatural in certain playing situations, so those who rely exclusively on instant, plug-and-play auto tracking may want to try before committing.

Pros & Cons

Pros

• Produces cinematic, oscillator-like synth sounds that expand a guitar's role beyond traditional effects.
• Layering and latch features let performers stack sounds and build evolving textures live.
• Effects loop allows creative routing and the ability to insert other pedals into the wet signal for unique patches.
• Adjustable attack and decay provide precise control over sustain character.

Cons

• Sensitivity and auto mode behavior have mixed feedback and may require patience to dial in for natural tracking.
• Not a simple replacement for standard modulation pedals if only classic chorus or flanger effects are required.
