Envelope and Filter Controls

ENVELOPE LOWER & UPPER Sliders — The Envelope sliders control the amplitude Attack or Decay of the Voices. The

LOWER slider controls the lower 5 voices (-2 Octaves to +1 Octave); the UPPER slider controls the upper 5 voices (+1 Octave +5th to

+4 Octaves).

The Envelope sliders have a center-detent; they click into place at the center of their travel. When set to the center-detent, there is no

change to the voices’ envelope: you have an instantaneous Attack and an infinite Decay. As you push the sliders up from the center, the

rate of Decay increases until the notes are barely audible. As you push the slider down from the center, the rate of Attack increases so that

your notes slowly fade-in.

ENVELOPE

ON LED —

Indic

ates when the Envelope section is in or out of the signal path. When the LED is lit, the Envelope is On

and in the signal path, when the LE

D is off, the Envelope is bypassed.

ENVELOPE Footswitch — Toggles the Envelope section ON / OFF.

FILTER FREQUENCY Slider — Controls the cutoff or peak frequency of the Low Pass Filter. As the FREQUENCY slider is pushed

upward, the cutoff frequency of the filter rises. This is a 2nd-Order filter.

FILTER RESONANCE Slider — Controls the Q or peak of the Filter. As the RESONANCE slider is pushed upward, the filter

emphasizes the cutoff Frequency more, creating an audible peak at the setting of the FREQUENCY slider.

All of the generated voices go through the Filter at all times. If you do not want to hear the effects of the filter, move the FREQUENCY slider

to its top position and the RESONANCE slider down to its bottom position.

Expression Controls

EXP. MODE Switch and LEDs — The HOG has 7 different Expression modes, this switch consecutively selects a mode, starting

with BEND 1 OCTAVE and ending with FILTER and then back to the BEND 1 OCTAVE setting. Each Expression Mode has it own LED which

lights up when the mode is selected. The 7 Expression Mode LEDs form a semi-circle around the EXPRESSION MODE Switch.

EXP. REVERSE Switch and LED — This switch reverses the direction of the Expression Mode currently selected. For example

with the EXP. REVERSE LED off, in BEND 1 OCTAVE mode, as you move the expression pedal from toe up to toe down, the pitch of the voices

will continuously rise until you hit 1 octave above. If you hit the EXP. REVERSE Switch and its LED lights up, as you move from toe up to toe

down, the pitch of the voices will continuously fall until you hit 1 octave below.

EXP. BUTTON Footswitch — This momentary footswitch enables you to take advantage of the 7 Expression Modes without

needing an Expression Pedal. Pushing down on the EXP. BUTTON is equivalent to the toe down position of the Expression Pedal. Taking

your foot off of the EXP. BUTTON is equivalent to the toe up position of the Expression Pedal.

The 7 Expression Modes are as follows (all descriptions assume you are using an Expression Pedal):

BEND 1 OCTAVE — Continuously bends all of the generated voices up to 1 Octave UP (or DOWN with EXP. REVERSE LED ON). This

is similar to using the whammy bar on a guitar or pitch bend wheel on a synthesizer. You can use this effect to obtain intervals that are

between the original note, the perfect 5th and the octave, for example, you can set the expression pedal to obtain a major 6th interval.

BEND 1 STEP — Continuously bends all of the generated voices up to 1 Step UP (or DOWN with EXP. REVERSE LED ON). Same effect

as B

ND 1 OCTAVE except the range is limited to just 1 step or the major 2nd interval. You can bend from an A note to a B note.

VOLUME — Continuously varies the volume of the generated voices. As you move the pedal from toe up to toe down, the volume will

increase from 0 to 1

00% (or 100% to 0 with EXP. REVERSE LED ON).

FREEZE + GLISS — The Freeze + Gliss function is a new expression mode that works a little differently from the other modes. When

the toe is up, you can play your instrument normally. When the toe is down, the HOG will freeze whatever notes you were playing at the

time of pushing the Expression pedal down. You can then play over these notes. In between toe up and toe down, the HOG will slide to the

new note you play, from the previous note you played. The speed of the glissando is determined by the position of the Expression pedal,

the closer the Expression pedal is to toe do

wn, the slo

wer the slide speed will be. For example, if you play an A note and then move the

Expression Pedal down to 50%, it will freeze the A note. If you then play an E note, the HOG will slide up to the E note. This function is

similar to portamento on a synthesizer. Freeze + Gliss is a very tricky mode, it takes some time to master it. It can be frustrating at first but

once you get it, it will open new doors to how you play guitar.

Please note: Moving the Expression Pedal to the toe up position erases the frozen note in memory.
