Voltage Requirements
If your pedal is capable of operating using a standard 9V battery, then it is safe to say that
you can power the pedal with 9 volts. If your pedal is powered using two 9V batteries
then it requires 18 volts. If your pedal cannot be fitted with a 9V battery, take a look at
the manufacturer’s recommended power adapter for the pedal, which usually provides
specifications including the output voltage of the adapter. If you are unable to determine
how much voltage is required for a pedal, take a look at the pedal’s user manual or
contact the pedal manufacturer. Also, if you happen to have a multi-meter, there are ways
of determining how much voltage a pedal requires. Information on how to perform these
tests can be found online.
Some analog pedals can operate within a range of voltages, but the sound characteristics
of the pedal may depend on the voltage supplied.
A pedal’s headroom is usually directly related to the voltage which the power supply is
supplying to the pedal. From an audiophile standpoint, higher voltages translate to less
likelihood the pedal will run out of headroom and cause “clipping” distortion, thereby
