GETTING STARTED
Connect to a power source
A 9V DC power adapter or a USB port
(using a Micro USB cable) can power
BIAS Modulation. You’ll find both power
connections on the pedal’s rear panel.
To power the unit with a 9V DC adapter,
insert the power plug and connect the
power adapter to an electrical outlet.
To power the unit via a USB port, insert
the Micro USB cable into the pedal and
connect the other end to a USB port on
your laptop or desktop computer.
During the booting stage, all LEDs on
the control panel will flash red and blue,
indicating that the pedal is booting up.

Signal Connection
Here are two basic ways to connect BIAS
Modulation in your signal chain.
1. Place the pedal in the signal chain
before your guitar or bass amplifier. This
will produce the pedal’s modulation
effects before the signal enters the
amplifier. Make sure to keep the pedal’s
gain low with this setup or the sound
might get out of control.
2. If you have an amplifier that comes with
an effect loop, you can connect BIAS
Modulation to the effect loop to create
modulation effects between the amp’s
preamp and power sections. In this
setup, your modulation effect will be
applied after the gain/overdrive stage and
will typically sound more natural than with
the first setup noted above.
*Note: BIAS Modulation provides either True Bypass or
Buffer Bypass for you to choose from (please refer to the
Bypass Mode section of this manual). If you have a lengthy
cable and a long signal path and want to preserve high
frequencies, Buffer Bypass will be most suitable for your
needs. On the other hand, if you want to tone down the
harsh top end of your sound, True Bypass might fit your
needs better.
*Note: When the pedal is on, the wireless LED will begin to
pulse softly, indicating that the pedal is on standby and
ready for use.
