Using this capo is a breeze. First, open the capo and place it on the desired fret of your 6 - string acoustic or electric guitar. Then, use the micrometer adjustment mechanism to set the right tension for your strings. You can play around with it until you find the sweet spot. When you're done playing, just remove the capo gently. As for maintenance, keep it clean by wiping it with a soft, dry cloth regularly. Avoid exposing it to extreme temperatures or moisture. If you notice any issues with the adjustment mechanism, don't try to fix it yourself; reach out to the manufacturer instead.
