OVERDRIV (OVERDRIVe)
In this mode, you can change the settings relating to each Effect for Overdrive and
Vibrato/Chorus.
To locate this mode:
1. Touch the [MENU/EXIT] button to display the MENU, select PAGE C by the [PAGE] button,
and then touch the [1] OD/VIB button.
2. Or, hold down the [TUBE AMP] button for a while.
1. PREAMP - TYPE
This is for choosing the Tube Amp Circuit.
SS

-U7-U7
-U7-U7
-U7: This is an amplifier with only one circuit, same as the
general overdrive effects.It treats all tonal range by 1
circuit by using the 12AU7.

X7X7
X7: This is an amplifier with only one circuit, using the
12AX7.
DD

-UX-UX
-UX-UX
-UX: This is an amplifier with 2 circuits for two different
bands. The 12AU7 treats the bass band and the 12AX7
treats the treble band.

XUXU
XUXU
XU: This is an amplifier with 2 circuits for two different
bands. The 12AX7 treats the bass band and the 12AU7
treats the treble band.
2. BIAS U
This parameter finely-adjusts the bias voltage of the tube 12AU7.
The setting range is -32 to +31.
3. BIAS X
This parameter finely-adjusts the bias voltage of the tube 12AX7.
The setting range is -32 to +31.
4. DRIVE
This is for adjusting the Overdrive Value.
The higher the value gets, the more distortion you can get.
This is linked with the [TUBE OVERDRIVE] knob on the front
panel.
5. EXPRESSION
This is for varying the Overdrive value by operating the Expres-
sion.
EXEX

-OD: If you operate the Expression, not only does the vol-
ume change, but also the distortion.

-EX-EX
-EX-EX
-EX: The Expression affects only the volume and not the
distortion value.
6. BLEND
This is for setting the Tone Range for Distortion.
The setting range is 0 to 63. The higher the value, the more the
treble will distort. The lower the value gets, the more the bass
will be distorted. The treble and bass distortion effects are equal
at 32.
NOTE: This parameter functions when the Preamp - Type (1) is at
“D-UX” or “D-XU”.
7. CROSSOVER
Here you can set the Crossover Frequency of two bands of the
Tube-Amp circuits.
The setting range is 125 - 800 Hz.
NOTE: This parameter functions when the Preamp - Type (1) is at
“D-UX” or “D-XU”.
NOTE: The parameters in these modes are Preset Parameters and
are recorded to each Combination Preset.
Please understand that the tone color or the depth of
Overdrive varies product from product even if the pa-
rameter value is the same, as the characteristic of each
tube is different, from piece to piece.
USING THE EQUALIZER TOGETHER
If you distort the sound by overdrive or by changing
the bias, new harmonics are added. This means, you
can expect colorful change of tones by the equalizer.
For example, if you set the middle frequency at “1.0kHz”
and the middle gain at “+9”, you can obtain a sound
with an clear interval feeling at the closed voicing, too.
