Can the Ernie Ball Volume Pedal be used as an expression pedal?
Normally the answer is no. Our volume pedals very simply require a signal input into one jack and an output is sent out of another jack. Most expression pedals are sent a single TRS cable from the device it is to control which both sends and receives an electronic signal. These are two markedly different functions and one cannot be substituted for the other without intense modification. An expression pedal controls the amount of voltage that allows certain functions, such as, delay, distortion levels, volume, etc. in a keyboard or an effects processor to perform to whatever parameters the user sets it up to do. Our pedal may work as an expression pedal, but the manufacturer usually suggests what type of pot needs to be used, 500k, 250k, 25k, etc. in a pedal, keyboard, or an effects processor. The pedal might require a more sophisticated design. It is best to contact the manufacturer to determine what type of pedal is necessary.
