Th is allows you to turn Overdrive “ON” or “OFF.”
TYPE
Settings: Tube, Solid, Clip
Th is allows you to adjust the character of the Overdrive.

DRIVE
Setting Range: 0 ~ 127
Th is allows you to adjust the amount of the distortion.
A higher value results in more distortion.
CROSSOVER FREQUENCY
Setting Range: 400 ~ 14.7k [Hz]
Th is allows you to adjust the upper limit of the frequency range receiving Overdrive.
BLEND
Setting Range: 0 ~ 127
Th is allows you to adjust the balance between dry and Overdriven sounds.
At “0” the sound is “dry.” At “127,” only the Overdriven sound is heard. Th e numbers
in between allow mixing of dry and Overdriven sounds.
NOTE: The mixing rate may not always be “1:1” if the value is set at 64 due to diff erent
envelopes between dry and Overdriven sounds.
EXPRESSION CONTROL
Th is allows you to adjust the relation between Expression and the Overdrive eff ect.
EX-OD .............. Both volume and distortion will changed by the Expression.
OD-EX .............. Only volume will be changed by the Expression.
OD Only .......... Only distortion will be changed by the Expression.
Input ................ Similar to OD ONLY, but with a smaller amount of change.

CROSSOVER FREQUENCY
In addition to distortion, the Overdrive eff ect also
introduces harmonics (overtones) into the sound.
Some of these harmonics may be undesirable and
create harmonic interference between dry and
overdriven sounds.
By using the Crossover Frequency Parameter to
limit the amount of upper frequencies receiving
Overdrive, you can minimize or eliminate harmonic
interference and create a more pleasing sound.
