Another Amazingly Unique Effect From ehx

It's not often a truly unique guitar effect comes along, like the Electro-Harmonix Superego synth engine pedal. The Superego guitar pedal is part synthesizer, part sustainer, and part sampler, allowing you to "freeze" your guitar sound and create layers of sustained soundscapes. You can sustain chords for etheric pad-like effects, or play synthesizer-like leads on your guitar. You can even sustain a note or chord, then "freeze" it while soloing over it. With all-analog circuitry, a built-in effects loop, and a totally original sound, you'll love exploring the possibilities of the Electro-Harmonix Superego synth engine pedal.

Electro-Harmonix Superego Synthesizer Pedal at a Glance:
  • Keyboard-like effects from your guitar
  • Three modes cover a wide range of uses
  • Built-in effects loop
Keyboard-like effects from your guitar

The Electro-Harmonix Superego uses a sample-and-hold circuit to grab a snippet of your guitar's signal, and sustains it to create a pad-like cloud of sound. If you're playing rhythm, the Superego can add depth to your arrangements that you'd normally only get with a keyboard player. When you play lead, you can create synthesizer-like tones that have a character all their own.

Three modes cover a wide range of uses

To get the most out of the Electro-Harmonix Superego you'll want to explore the three operation modes. Momentary mode means the effect is only active when you step on the footswitch, and returns to bypass operation when you lift your foot - it's perfect for sustaining the last note of your solo, for example. Latch mode sustains anything you play while holding down the footswitch like Momentary mode, but continues sustaining until you turn the effect back off - you can use this mode to "record" a layer of sound to play over. And finally there's Auto mode, which doesn't require you hold the footswitch to apply the effect - just play through the Superego, and it'll transform whatever you play into an entirely new sound.

Built-in effects loops

If you like the unique sound of the Electro-Harmonix Superego, then you'll love that it has a built-in effects loop. Use this to add yet another sonic dimension to your tone by adding a delay pedal, chorus effect, reverb, or other effect to the Superego's signal. Whatever effects you add to the Superego's effects loop will only process the wet signal of the Superego, which means you can create custom sound effects that wouldn't be possible with a single input and output.

Electro-Harmonix Superego Synthesizer Pedal Features:
  • Sample-and-hold guitar effects pedal creates synthesizer-like sounds
  • Three different operation modes give you three very different playing experiences
  • Controllable glissando lets you "slide" between notes
  • Infinite sustain for notes and chords
  • Latch mode allows you to record "layers" of sound and play over them
  • Built-in effects loop lets you add additional effects to the Superego's wet sound
  • 9V power supply included

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

My secret weapon

The original egx HOG (grandfather to the pog2) had a quirk where if you set the sliders perfectly, you could create this is harmonic noisy feedback that would still be in tune with what you were playing. I loved that feature, and it made it worth owning the $ pedal (which also took up the real estate of 8 normal size pedals). I never got into the freeze pedal because it seemed boring in comparison, but this pedal gets me to almost the exact same tone as the HOG did. I've honestly never used the auto--I use it as an embellishment or to give more feeling, or sometimes just more noise in a song. It works especially well during any buildups in a song, taking things from whisper quiet to a wall of noise. it's the one thing I consistently get asked about after playing a show--everyone wants to know what I was using to get the sounds I do.
Rated 5/5

Cool tool for soloing practice

Allows you to play a chord and sustain it indefinitely. Unlike structured backing tracks, you control when the chord changes and what it will be. I am sure there are other uses for this pedal, but I haven't had a chance to explore them yet.
Rated 5/5

Awesome

When I first plugged into this pedal, I was underwhelmed. It is NOT a plug and play piece of gear. However, once I kept playing and adjusting the levels, the sounds got better and I began to like it asca result. Then I hooked my spare delay into the loop and, it came alive! Use the loop, it takes the unit to a whole new level. I have a nova repeater set to reverse mode and the vibrato set pretty high, kill-dry on.

The feature that took the most getting used to was the Auto mode, though. But again, stick with it and you will have an awesome expression tool on your hands.
Also, I am not an ambiance guitar player by trade. I do not use this to achieve synth tones. The way I use this is to have a pseudo organ/keyboard in the background. As that, it shines for me.

Very Unique Pedal

There is a copy of just about every effect. I don't know of anything that is like this pedal. To be able to play and sustain a chord and then play over it is probably specific to this pedal and could be an effect that sets you apart from other guitarist.

Your Instrument's Third Eye

First of all, The reason I bought this pedal is that my pedal board needed a shoegazey, ambient sound. The numerous analog delays, some digital delays, reverb pedals, chorus and other modulation pedals, plus a bunch of pedal I made were not giving me the sound I wanted. But then magicaly, a week later new superego pedal came out on the electro-harmonix website. Once I heard it, I was amazed that it would give me the sound in my head that I was looking for. So I spent some money and bought it.
I have played with the electro-harmonix freeze pedal and loved it, but what made me want to spend the extra money was the extra features such as the Momentary, Latch, and Auto mode toggle switch, the Speed / Layer knob, the Gliss control, and what I find the coolest, is that the send and return jacks allow you to modify the wet signal with other pedals, making your options limitless. And you should experiment with other instruments through this pedal, like a synth, sampler, bass, yuke, or whatever has a 1/4" output.
The only minor cons I would say this pedal has is one, it doesn't have true bypass but only because of the way the stomp switch works, such as in momentary mode where once your foot is off the pedal, the frozed signal starts to decay. But it would be nice if the put a second stomp switch that was a 3PDT so you could truely bypass the signal. The second con, which really doesn't matter to me at all but may matter to other people is that you can't put a 9v battery in it. But it comes with a 9.6v DC 200mA power supply, which is pretty much the standard for most guitar pedals. The two cons are so minor that I would still give the pedal five stars.
There is no other pedal like this and it will add so many more options on your pedal board or synth setup . I pensonally love this pedal, and many of the guitarist who record at my studio love it too. Watch the videos and give the pedal a listen before you get it, but the videos can't even show you 1/100th of what you can do with this pedal.First of all, The reason I bought this pedal is that my pedal board needed a shoegaze, ambient sound.

What Do Our In-house Gear Experts Think?

Ashton Boyd

As a keyboard player and aspiring guitarist, I was blown away by how the SuperEgo blurred the lines between the sound of the two instruments when tried on each. The real fun comes with the infinite sustain settings, where you can stack your instrument and maximize your output. This is an exciting pedal to have in your rig!
