Introduction
Owner’s Manual
The Vowel is an active volume/classic wah-wah combo pedal features extremely lightweight casing and a small, pedalboard-friendly
footprint. 100% analog signal path and selected smooth taper ensures pure signal-thru and precise response.
READ CAREFULLY BEFORE PROCEEDING
Please keep this manual in a convenient place for future reference.
Power Supply
Always use a DC 9V center negative AC adapter. Use of an adapter
other than that specified could damage the unit or cause malfunction and
pose a safety hazard.
Always connect the AC adapter to an AC outlet that supplies the rated
voltage required by the adapter.
Disconnect the AC adapter from the AC outlet when during lightning
storms or not using the unit for an extended period.
Connections
Always turn off the power before connecting or disconnecting. Make sure
to disconnect all cables and AC adapter before moving the unit. This will
help prevent malfunction and damages.

malfunction:
● Extremely hot or cold places

● Magnetic fields
● Near heaters and other heat sources
● Sandy or dusty places
● Places that are extremely humid or exposed to splashing water
● Places with lots of vibrations
Electrical Interference
Devices that are very susceptible to interference or that emits powerful
electromagnetic waves (e.g. radios and TVs) should not be placed near
this unit, as interference could occur. Electromagnetic interference could
cause malfunction and could corrupt or destroy data.
Always operate this unit at a suitable distance from these devices.
Handling
Do not apply excessive force to the switches and other controls,
exposing the unit to strong impacts, which could cause it to break.
Do not put foreign objects or liquids into the unit.
Never open the case or attempt to modify the product in any way since
