Notes: Instantly create matching harmonies to what you play.

The EHX Intelligent Harmony Machine instantly creates matching harmonies to what you play. It's like having one - or even two - guitarists jamming with you at the same time and always in perfect sync. The Intelligent Harmony Machine opens a door to the music of great multi-lead guitar bands and multi-part harmonized solos. Plus, its ability to apply harmonies ranging from simple to sophisticated will totally transform what you play. Of course, it also boasts EHX's renowned impeccable tracking and genuine musical tone.

Select your key and the Intelligent Harmony Machines will generate single note, diatonic harmonies* with a huge range of choices that includes both two- and three-part harmonies. Here are your choices:

1: 6th Down
2: Perfect 4th Down
3: 3rd Down
4: 3rd Up
5: Perfect 4th Up
6: Perfect 5th Up
7: 6th Up
8: 7th Up
9: 3rd Up + 5th Up
10: 3rd Up + 7th Up
11: Perfect 5th Up + Octave Up

These sound so cool that EHX have included them as extra options for the multi-harmony parts (selections 9, 10 and 11) to give you even more choices:

9 optional: 4th Down + 3rd Up
10 optional: 3rd Up + 6th Up
11 optional: Octave Down + 5th Up
9 optional: 6th Down + 4th Down
10 optional: 3rd Down + 3rd Up
11 optional: Octave Down + 4th Down
The Intelligent Harmony Machine also performs perfect polyphonic pitch shifts so the pitch shifts you dial up are applied to chords as well as single notes. We've even included a Major/Minor switch so you can select whether 2nds and 3rds will be major or minor. Here are the interval selections that are available:

1: Doubler
2: Perfect 4th Down
3: 3rd Down (minor on major)
4: 3rd Up (minor or major)
5: Perfect 4th Up
6: Perfect 5th Up
7: 2nd Down (minor or major)
8: 2nd Up (minor or major)
9: Octave Down
10: Octave Up
11: Perfect 5th Up + Octave Up

The Intelligent Harmony Machine's Moment Mode lets you instantly change pitch by simply depressing the pedal's footswitch. The pitch shift is engaged as long as you hold down the F/S. There's also an option so you can apply a user-set sweep time between dry and effect. Choose instant pitch changes or control the time it takes for the Intelligent Harmony Machine to sweep up and down between the set interval and the dry signal!

EHX Founder, Mike Matthews said: "We designed the Intelligent Harmony Machine for the player who craves maximum power, but in a minimal footprint. You'll dig its sweet, musical tone and spotless tracking!"

*Diatonic harmony means notes within a specific key that relate to each other.

Compact harmony generating, pitch-shifting powerhouse
Impeccable tracking and superb musical tone
Two distinct modes: Intelligent Harmony and Polyphonic.
Intelligent Harmony Mode generates diatonic harmonies in a set key based on the single notes you play. Key Selector and #/- switches provide access to all 12 keys.
In Polyphonic Override Mode you can play single notes and chords. The IHM's 11-position Interval Selector switch lets you select the harmony.
In Momentary Mode the effect is only active when the footswitch is depressed. Choose from instant shifts or set the time it takes the signal to sweep up and down.
Mix control sets the mix between your dry and shifted signals. Dry output adds signal routing and control options and flexibility
Comes equipped with an EHX 9 Volt power supply, can also run on 9 Volt battery

Notes: The MOP-D10 is a multi-output power source that was developed by EHX engineers to provide a player with noise-free pedal operation. It features ten isolated 9VDC outputs that handle the most popular power requirements: 4x100mA, 2x250mA, 2x300mA and 2x400mA.

From its premium analogue power path featuring low-noise linear regulators to its custom-wound toroidal transformer, the MOP-D10 is designed to let a pedal user achieve a sonically pure signal path. Unlike many other multi-output power supplies which rely on switching power conversion, the MOP-D10's transformer-based power conversion is significantly less susceptible to spurious noises leaking into the audio path. An AC Voltage Selector Switch also ensures the MOP-D10 can be used with a range of voltages commonly found around the world.

Each of the MOP-D10's outputs is center-negative and all output power jacks are isolated from each other. The dimensions of each output connector are 5.5mm x 2.1mm. The unit is supplied with a 6' detachable power cord and ten 24" long DC power cables equipped with one straight and one right-angle end. It also includes hardware for pedalboard mounting.

Notes: The smallest member of the polyphonic POG clan provides impeccable tracking and sound!

The EHX Nano POG can simultaneously generate multiple octaves from your input signal. Whether you play single notes, arpeggios, or full chords, the Nano POG will precisely track every note or chord that you play.

With the Nano POG, you can mix together your dry signal with two different octaves (one above and one below your original note) to create totally new, inspiring tones.

Separate level controls for dry, sub octave and octave up plus an extra Dry out and silent footswitching provide the perfect formula for this compact jewel.

Notes: Transform your electric guitar into a sitar!

Very few instruments offer as much harmonic and dynamic flexibility as a sitar. Electro-Harmonix has streamlined the essence of the sitar into a compact enclosure that offers a polyphonic lead voice and tuneable sympathetic string drones that dynamically react to your playing. With the EHX Ravish Sitar Emulator, you can create your own custom scales for the sympathetic strings while you set the decay time for the lead voice.

Two expression pedal inputs allow you to bend the pitch of the lead voice and control the volume of the sympathetic strings simultaneously. These unique controls offer the player the ability to program the Ravish to become a totally unique and organic instrument unto itself.

The Ravish is a truly new design with the flexibility to be a crossover tonal wonder.

Notes: The polyphonic STRING9 String Ensemble transforms a guitar into nine different string ensembles and string synthesizers while requiring zero modifications, special pickups, or MIDI implementation. It relies on the same technology powering all EHX 9 Series pedals. In a 9 Series first, the STRING9 includes the signature EHX Freeze effect on 3 of the presets to sample and hold notes and chords with infinite sustain.

A rotary switch on the STRING9 allows the player to select the sound of their choice, as follows:

SYMPHONIC: Re-creates the sound of a large symphony orchestra and features an octave down effect on the lower range of the guitar for a full sound
JUNE-O: Emulates the Junor analogue string synthesizer sound
PCM: Sound of a small string section sampled by a vintage PCM keyboard producing a warm vintage string sound
FLOPPY: Emulates the sound of an Orchestronr optical disc playback sampler, warble included
AARP: Emulates the classic ARP Solinar string synthesizer
CREWMAN: Emulates the Crumar Performerr analogue string and brass synthesizer; Floyd in a box
ORCH FREEZE: Orchestral sound with EHX Freeze effect
SYNTH FREEZE: String synthesizer sound with EHX Freeze effect
VOX FREEZE: Mellotronr choir and strings sound from the EHX MEL9 with EHX Freeze effect
The pedal is equipped with independent Effect and Dry volume controls so players can precisely tune their mix at the Effects output jack, plus a Dry output jack that always outputs the input signal at unity gain.

Controls 1 and 2 have been designed to adjust specific parameters for each of the nine programs adding usability and flexibility to each sound.
