Powering the Wahoo
The Wahoo can be powered by batteries, by a 9V
DC
power supply (neither of these is supplied), or
by USB . Select one of the following:
• insert 4 AA batteries (alkaline can be used, but we recommend rechargeable NiMH batteries)
into the battery compartment in the base of the Wahoo. WARNING: observe correct polarity!
• plug the output of a 9V DC power supply into the port labelled DC on the back of the Wahoo.
The 9V DC power supply that you use should be capable of providing 500mA and have a
2·1mm centre pin connector. Note that the Wahoo has been designed so that either polarity
(tip-positive or tip-negative) can be used.
• plug a USB cable connected to your computer or a USB power supply into the port labelled USB
on the back of the Wahoo. If a
USB
hub is used, it may need to be a powered hub to ensure it
can provide enough current to the Wahoo.
Note that there is no problem if you connect all three power sources at once. The DC supply takes
priority, then
USB
, then the batteries. This ensures your batteries are not drained when they are not
needed and allows you to connect via USB without using USB power when a DC supply is present.
The Wahoo is switched on when you connect USB or DC . When running from batteries, the Wahoo
is switched on when an instrument cable is connected to IN . To prolong battery life, disconnect the
cable from
IN
when the Wahoo is not being used.
Enabling and bypassing the Wahoo
The main footswitch
LED
shows the status of the Wahoo effect.
When this LED is off, the effect is completely bypassed and the input ( IN ) is directly connected to the
output ( OUT ). This connection is known as a true-bypass connection because in this state none of
the Wahoo electronics are connected to the signal which keeps your original guitar/bass signal as
pure as possible.
When this
LED
is on, the signal is passed through the Wahoo and the output (
OUT
) is the effected
(filtered) signal.
The effect is enabled and disabled by briefly pressing the footswitch. Alternatively, when the
footpedal is moved to the toe-down position, the effect will automatically enable. This emulates the
behaviour of a classic Wah pedal which has a footswitch placed under the footpedal. Note that this
feature can be turned off using the custom settings (page 27).
Top Tip: If you are using the Wahoo on stage, use a DC power supply and batteries. That
way, if the DC power supply is pulled out for any reason, the Wahoo will switch to
batteries and you will, in effect, have an un-interruptible power supply.
