Critic Reviews

Electro-Harmonix Superego Pedal Review - Premier Guitar

premierguitar.com

The Electro-Harmonix Superego Synth Engine is a dream for sonic explorers, offering near-infinite tonal possibilities in a compact form. With its innovative auto mode, gliss control, and effects loop, it allows guitarists to dive into synth-like textures and ambient soundscapes. However, the pedal's high threshold for sound sampling and sometimes harsh high frequencies may require careful adjustment. At $212, it's a bit of an investment, but for those who love to experiment with textures and transform their guitar sound entirely, it's a worthwhile addition to the pedalboard.

YES

Basically I use this pedal to form ambient pads and long sustained chords and solos. It's very particular and it's beautiful to twin its knobs during your playing. The Superego is the main pedal used on the track "Introduzione" by Le Piccole Morti: https://lepiccolemorti.bandcamp.com/track/introduzione

Secret Weapon

I've been using this to freeze the tonic chord of some songs add it as a layer in the background of songs. It adds a lot of nice depth to the mix.

pitchy

Its the Freeze on stereoids!

A great little bit of kit, which works like the EHX Freeze, but is expanded with additional in/outs and is much more controllable over the sound whether you're freezing chords or making crazy sounds. Great addition alongside POGs.

biscuitbarn

instant love

For the style of music i've been playing, this was a no-brainer. the freeze is a great concept and this takes it even further. Right now, I have a pitch fork in its effects loop and makes for some great organ like sounds.

courtland_adams

Cool, but hard to find a use for

I've had this for a while and absolutely love it. You can get some awesome sounds out of this when you really start experimenting,but trying to find a practical use for it can sometimes be quite hard. Good fun though!

marcosdeker

So original

It's like an evolution synth-type of the Freeze. Lots of options. They just have to fix the switch sensibility, it's the worst of this pedal.
