Stop taping up your gear! The Loknob upgrades the knobs on your stomp box or amp with a lockable aluminum knob that features a ring of teeth that aligns with a second ring of teeth that adheres to your chassis. Once installed (a task made simple with the included hex wrench), pull up on the knob to fine-tune your setting and push the knob in to lock. Knobs are available in ¾" and ½" versions, and are removable. Prices start at $13.99; loknob.com.
