Using the D’Addario Auto Lock Guitar Strap is easy. First, find the strap buttons on your guitar. The spring - loaded latch of the strap will automatically clamp down on the buttons when you press it on. To remove the strap, just pull the latch gently to release it. When using, make sure the strap is adjusted to a comfortable length for you, between 35' and 59.5'. For maintenance, keep the strap clean by wiping it with a soft, dry cloth regularly. Avoid exposing it to extreme heat or moisture as it may damage the padding and the woven material. With proper use and care, your D’Addario Auto Lock Guitar Strap will last a long time.
