Electro-Harmonix was founded in 1968 by Mike Matthews. EHX has always been a synonym for the highest quality in the guitar world. EHX’s first market breakthrough was the legendary Big Muff fuzz pedal. Another legendary pedal released in 1976 was an analog delay called Deluxe Memory Man. Both Big Muff and Deluxe Memory Man are still in production.

Today EHX is one of the largest vacuum-tube suppliers in the world. Sovtek is also a company that belongs to Mike Matthews.

It seems that every pedal ever made by EHX deserves attention and merits being put on your pedal-board. Here I will point out several widely used pedals with Ambient guitarists.

• Stereo Memory Man with Hazarai | Digital Delay/Looper - - It's a looper, it's a multi-tap delay, it's an echo with reverse... As a Looper it has up to a full 30 seconds of loop time. World class echoes with modulation and reverse. Up to 3 seconds of: stereo echo with adjustable reverberant washes, stereo multi-tap delay with adjustable number of taps and taps amplitude envelope, seconds of intelligent reverse echo. Tap tempo and more…
• 95000 | Performance Loop Laboratory – This looper was highly estimated on NAMM 2018 and it’s really one of the most powerful loopers to date, featuring six mono tracks and one stereo mixdown track per loop. It will record up to 375 minutes and 100 loops with a 16GB Micro SD card and switching between loops is quick and easy.
• POG2 | Polyphonic Octave Generator - Back in 2005, Electro-Harmonix unveiled the original POG, a polyphonic octave generator that enabled guitarists to conjure everything from the surreal jangle of an 18-string guitar, to rich, thick walls of symphonic sound. POG2, released in 2009, went further. New attack delay slider to control the fade-in speed of the octaves for smooth swells. Second sub-octave was added. The 2-pole resonant low-pass filter now includes two additional Q modes. Enhanced detune to further refine your sound. Flawless polyphonic glitch-free tracking.
• Superego+ | Synth Engine / Multi Effect – The pedal, released in 2017, is built on the synthesis platform of the award-winning Superego. Designed to create synth effects, sound layers, glissandos, infinite sustain and more. Effects section featuring 11 effects types was added.
• Cathedral | Stereo Reverb – Though the pedal was launched in 2009 and many new superb reverbs appeared on the market it is still challenging. 24 bit AD and DA converters / True stereo inputs and outputs / 8 programmable reverb styles (Grail Spring, Accu Spring, Hall, Room, Plate, Reverse, Grail Flerb, Echo) / Tap Tempo to set pre-delay section / Hold tap tempo for infinite reverb. https://www.ehx.com/products/cathedral

Controllable harmonic intervals: -2 octaves, -1 octave, original note, +5th, +1 octave, +1 octave +5th, +2 octaves, +2 octaves +3rd, +3 octaves, + 4 octaves. 7 Expression Modes. Freeze expression mode holds a note or chord-play over it or slide to new notes like a keyboardist playing portamento. Amplitude envelope lengthens a note’s attack for swells or increased decay speed. Dedicated resonant filtering with sweepable frequency control. Separate lower and upper harmonic amplitude envelopes.
• SYNTH9 | Synthesizer Machine - The polyphonic SYNTH9 Synthesizer Machine transforms your guitar or bass with 9 presets to emulate the most sought after, vintage synthesizer sounds ever! From searing lead synths to spacey synth pads and deep, funky, synth bass grooves.
