Using the Ernie Ball Pegwinder Plus is a breeze. First, use the integrated bridge pin puller to remove the old bridge pins. Then, start loosening the old strings with the pegwinder. Once the strings are off, insert the new strings and use the pegwinder to wind them up tightly. Remember, hold it with the soft grip for comfort. When it comes to maintenance, keep it clean and dry. Avoid dropping it on hard surfaces as it might damage the ball bearing design. If you're not using it, just tuck it away in your gig bag or case for easy storage.
