OKNOB-CLASSIC Pedal Knob Add-On Turner Boss MXR : OptionKnob Popular

The OKnob uses a friction-based grip to replace your factory knob and fit tightly in its place. It is made out of very durable materials so that it can withstand being tossed around in your gig bag.
Traditional effects pedal knobs may be different sizes on the outside, but they all have a very similar size hole on the bottom side of the knob. Option Knob designed 2 different OKnobs, the Classic and the Boutique, which cover the entire range of knob shafts so that it will ensure a snug fit when you replace your factory knob. In seconds you can install the option knob on your favorite vintage pedal, or on your brand new pedal that you bought today!
