Product Overwiew
Thank you for choosing an Onerr product.
The wah wah effect was made popular by the most influential guitar players of the late 60s.
The Cryin' CB-01 wah wah was designed to be used with
guitar, and its modern design and solid
construction will give years and years
of outstanding performance.
The TRUE BYPASS switch keeps your
guitar tone unaffected while working
in by-pass mode.

Amplifier
A wah wah effect is an active sweepable bandpass
filter.
With the heel down, low frequencies will be
more accentuated.
With the toe down, high frequencies will be
more accentuated.
4- To turn your wah wah pedal OFF, just push the
toe of the pedal all of the way down until you
hear or feel a little click. This indicates that
now you are working in bypass mode.
Try also connecting your wah wah pedal after
your effect pedals. The wah wah effect sounds
different when used after distortions and overdrives
compared to when used before them.
This method will not cause any damage to your
equipment, so don't be afraid to experiment!

Warning
The input jack also serves as a power switch. Power is turned on when an instrument plug is inserted into the input jack
and is it turned off when disconnected. When this unit is not in use you should disconnect any cord connected to the input jack.
Care and Maintenace:
Use a soft, dry cloth for external cleaning. Do not use chemical products, which may damage its rubber and plastic parts.
The CB-01 wah wah pedal uses an internal long life potentiometer that controls the sweep of the wah wah filter.
It may eventually present unexpected noises due to dust and dirt accumulation. A “scraping” sound will become audible
through your amplifier.
If you experience this problem, try cleaning the potentiometer with a spray contact cleaner.
Just remove the back aluminum cover for potentiometer access. Apply a fine spray of electronic contact cleaner with
lubricant directly inside the potentiometer. Move pedal back and forth to ensure penetration of cleaner.
Put the aluminum plate back and test the pedal.
If the results are unsatisfactory, seek authorized service for potentiometer replacement.
Notes:
Only use reliable cords to connect your pedals.
Before powering your pedals, make all necessary linking connections. If you need to change any connection, do not forget to turn
the power off in order to prevent any possible damage to your units.
Only use regulated adaptors for best performance.
Do not worry if you accidentally change the input to output cord. This will not damage your unit. Just turn the power off and
reconnect it correctly.
