Dial and lock in your sound settings with the easy-to-install D'Addario Loknob Pro. Once in place, simply rotate the knob to click into the sound you need. For larger sound adjustments, lift the knob, rotate to your desired sound, and release. Loknob retrofits to most amplifiers, effects pedals, instruments, and live/studio gear.

As always, feel free to contact our store for more details, or with any questions.
