Expression Pedal:
　The Vocalist Live 4 can use either a standard passive guitar volume pedal or
a resistance-based expression pedal.
If using a standard guitar volume pedal, it should use a 250k Ohms or higher pot.
If using an expression pedal, it must offer a TRS connection and offer a minimum
resistance of 10k Ohms.
