1. Thru
The effect processor is bypassed.

2. Stereo EQ
This is a four-band stereo equalizer (low, mid x 2, high). Stereo 
signals (like certain piano sounds) are thus not combined to a 
mono signal before being processed.
● EQ Low Frequency (200, 400Hz)—Frequency of the low 

range you wish to boost or cut.

● EQ Low Gain (–15dB~0~15dB)—Gain of the low range. 

Negative values reduce the level.

● EQ High Frequency (2000, 4000, 8000Hz)—Frequency of 

the high range you wish to boost or cut.

● EQ High Gain (–15dB~0~15dB)—Gain of the high range. 

Negative values reduce the level.

● EQ Mid 1 Frequency (200~8000Hz)—Frequency of the 

middle range 1 you wish to boost or cut. This is a paramet-
ric EQ band.

● EQ Mid 1 Q (0.5, 1.0, 2.0, 4.0, 8.0)—Width of the middle 

range 1. Set a higher value for “Q” to narrow the range to 
be boosted or cut.

● EQ Mid 2 Gain (–15dB~0~15dB)—Gain of middle range 1.
● EQ Mid 2 Frequency (200~8000Hz)—Frequency of the 

middle range 2 you wish to boost or cut. This is a paramet-
ric EQ band.

● EQ Mid 2 Q (0.5, 1.0, 2.0, 4.0, 8.0)—Width of the middle 

range 2. Set a higher value for “Q” to narrow the range to 
be boosted or cut.

● EQ Mid 2 Gain (–15dB~0~15dB)—Gain of the middle 

range 2.

● Level (0~127)—Output level. Use this parameter to com-

pensate for exaggerated level differences resulting from 
the settings you made.

3. Overdrive
Creates a soft distortion similar to that produced by vacuum 
tube amplifiers.
● Drive (0~127)—Degree of distortion. Also changes the vol-

ume.

● Panpot (L64~0~63R)—Stereo location of the output 

sound. This is a mono effect that combines incoming sig-
nals. You can, however, place the processed signal any-
where between the left and right channels.

● Amp Simulator Type—Allows you to specify what kind of 

guitar amp will be simulated: SMALL: small amp, BUILT-IN: 
single-unit type amp, 2-STACK: large double stack amp, 
3-STACK: large triple stack amp.

● EQ Low Gain (–15dB~0~15dB)—Gain of the low range. 
● EQ High Gain (–15dB~0~15dB)—Gain of the high range.
● Level (0~127)—Output level. Use this parameter to com-

4. Distortion
Produces a more intense distortion than the above. The 
parameters are the same as for “3. Overdrive”.

5. Phaser
Adds phase-shifted copy to the original sound and modulates 
it.
● Phaser Manual (100~8000Hz)—Adjusts the basic fre-

quency that is modulated by the effect.

● Phaser Rate (0.05~10.0Hz)—Frequency, i.e. modulation 

speed.

● Phaser Depth (0~127)—Modulation intensity.
● Phaser Resonance (0~127)—Amount of feedback. Higher 

values create a rather more “synthetic character”.

● Phaser Mix Level (0~127)—Level of the phase-shifted 

sound with respect to the original signal.

● Panpot (L64~0~63R)—Stereo location of the output 

6. Spectrum
Spectrum is a type of filter that modifies the timbre by boost-
ing or cutting the level at specific frequencies.
● Spectrum 250Hz Gain (–15dB~0~15dB)

● Spectrum 500Hz Gain (–15dB~0~15dB)

● Spectrum 1000Hz Gain (–15dB~0~15dB)

● Spectrum 1250Hz Gain (–15dB~0~15dB)

● Spectrum 2000Hz Gain (–15dB~0~15dB)

● Spectrum 3150Hz Gain (–15dB~0~15dB)

● Spectrum 4000Hz Gain (–15dB~0~15dB)

● Spectrum 8000Hz Gain (–15dB~0~15dB)—Gain of each 

frequency band.

● Spectrum Band Width Q (0.5, 1.0, 2.0, 4.0, 8.0)—Simulta-

neously adjusts the width of the adjusted ranges for all the 
frequency bands.

7. Enhancer
This effect controls the overtone structure of the high fre-
quencies, adding sparkle and tightness to the sound.
● Enhancer Sens (0~127)—Sensitivity of the enhancer.
● Mix Level (0~127)—Level of the overtones generated by 

the enhancer.

● EQ Low Gain (–15dB~0~15dB)—Gain of the low range.
● EQ High Gain (–15dB~0~15dB)—Gain of the high range.
● Level (0~127)—Output level. Use this parameter to com-

8. Auto Wah
This effect controls a filter to create cyclic change in timbre 
(an automatic wah effect).
● Auto Wah Filter Type (LPF, BPF)—Type of filter. LPF: the 

wah effect is applied over a wide frequency range. BPF: the 
wah effect is applied over a narrow frequency range.

● Auto Wah Rate (0.05~10.0Hz)—Frequency, i.e. modula-
