The Option Knob is a revolutionary guitar effects accessory. It easily replaces the factory knob on your guitar pedal and allows you to have real-time control of your sound effects by using your foot, not your hands.
The Option Knob enables you to have more control over your sound while playing your instrument. It allows you to break into the full potential of your effects pedals through sound manipulation during live performances.
The Option Knobis available in two models. One model for traditional pedals with a .220-.235 pot shaft and the other for boutique pedals with a .235-.250 pot shaft. Click here for more info and ordering. Credit: Option Knob.
