Using the Fender Mahogany - finished Stratocaster Level - up Wall Hanger is easy. First, gather all the mounting hardware included in the package. Then, find a suitable spot on the wall where you want to hang your guitar. Mark the spots for the screws according to the hanger's holes and install the hanger securely on the wall. Next, gently place your Stratocaster on the hanger, making sure the headstock fits properly on the offset dowels. As for the pick holder slit on top, you can store your guitar picks there for quick access. When it comes to maintenance, since it's made of real wood, avoid exposing it to extreme humidity or direct sunlight, as this could damage the mahogany finish. Also, be careful when handling the guitar on the hanger to prevent any scratches on the wood. Remember, each hanger is unique due to the natural wood, so it might have some small differences from the photo you saw.
