Simble Overdrive - owner’s manual
Thank you for buying
the SIMBLE OVERDRIVE!
The SIMBLE OVERDRIVE is a transpar-
ent and organic sounding pedal with
wide dynamic range.
When you first plug in, please set the pedal
like this:
Now when you switch the pedal on/off, your
tone should not change. Your volume might
change depending how powerful the pickups
are on your guitar. Set the LEVEL to match
bypassed signal.
Now you have transparent tone from where
you can start working for your own tone.
Turn the SENSITIVITY CW to add more dis-
tortion and the LEVEL to set the output.
With the ACCENT knob you can adjust how
much you hear the pick attack on pedal input.
You can also brighten dark pickups with this.
Fully CCW there is no effect.
CONTOUR adjust the tone of the output signal,
turning it CCW you soften the output for jazzy
tone, darker harmonic and better match for really
bright amplifiers.
