Ernie Ball Stereo Vol/Pan NEW! The dual potentiometer has a 500k ohm resistance suitable for the audio path of passive or active instruments. Attached to the footplate is a switch that provides the user two operating modes (volume or pan). Use the A input / A output for the left channel and the B input / B output for the right channel for stereo signals. For use with stereo cable installations using TRS type stereo plugs, use the B input and B output. For use as a mono volume pedal, use the A input and A output. For use as a typical pan pedal, switch the toe tap switch to the pan position and use only the A input. The pedal will pan the signal between the A and B outputs.
