  • Accessories

10 faders control 10 intervals of pitch
10 intervals of pitch can be mixed by using 10 surface faders, which may then be played polyphonically with perfect tracking:

  • 1 octaves down
  • 2 octaves down
  • Original pitch
  • One Fifth up
  • 1 octave up
  • 1 octave + a perfect fifth
  • 2 octaves up
  • 2 octaves up + a major third
  • 3 octaves up
  • 4 octaves up

Six unique expression modes
Six unique expression modes are accessible via the Exp button, expression pedal, and MIDI. Octave bends, step bends, volume control, user defined Wah-Wah, Filter control, plus two unique freeze modes: With Freeze Gliss, an expression pedal freezes a chord while letting you play over it having your frozen notes gliss to meet your new notes. The Freeze Volume freezes a chord allowing you to control its volume, with an expression pedal, as you play on top of it.

Real-time manipulation
An external "whammy" pedal and a momentary surface mounted Exp button, allow for real-time access and manipulation of all of the above expression modes. A new level of performance interaction.

Dual envelope generators
Dual Envelope generators that work with both the higher and lower frequency ranges. Allows unique contours of attack and release in two different harmonic regions. 12dB per octave 2-pole low pass filter and resonance controls manipulate the tone while also being a critical element within the expression modes.

Store performance presets when you use the optional external Electro-Harmonix foot controller. 9LDC-500 power supply included.

Among the true giants in the world of guitar effects and pedal manufacturers is the great electro-harmonix, the same people who brought you the legendary Big Muff Pi, the Small Stone, and many other classics. So when I saw their newest and fanciest octave box, the HOG (Harmonic Octave Generator), which appeared to be a kind of POG (Polyphonic Octave Generator) on steroids, curiosity got the best of me. You can tell immediately with electro-harmonix units like the HOG that the idea is to encourage the player to get creative and see what uncharted psychedelic landscapes he or she can discover, and so I decided to buck tradition and plug in an acoustic guitar with a pickup. Like the POG, the HOG has sliders for the different octaves that it produces, in addition to the original note or notes. Unlike the POG, the HOG also has sliders for intervals (5ths in 2 different octaves above the note, and also a major 3rd, two octaves above the note). The tracking, whether you play chords or single notes, is right on, and there are two envelope generators (one for the upper five intervals and one for the lower five) so that you can smooth out the attacks and delays to blend the organ-like tones against your own guitar's tone to suit your taste. The effect is lovely and otherworldy at the same time, and there is also a low-pass filter with adjustable bandwidth to further dial in that perfect patch. Besides the sliders, the HOG comes with an expression pedal that controls any one of the seven expression modes, such as freezing a note or chords to play on top of, controlling the volume of the effected signal against the dry one, or sweeping the filter. One of my favorites so far is to set the expression mode to "step bend" (which bends the post-effect note or notes one whole-step if you step down all the way on the pedal) and then just nudge it slightly to give a chorus-like detuning effect. I'm sure it's only one of many little tricks the creative player will discover with this unique unit. In a world where better-sounding and more feature-laden software suites for guitar show up almost every day, the HOG, with its 16 sliders, pedal, and powerful expression modes, seems likely to take its place among the classics of the real-world effects units.
