Using this 1/4 (6.35mm) DIY stereo plug is easy. First, gather the wires you want to use for your audio cable. Then, solder the connector to the wires carefully. Make sure the soldering is firm so the connection is stable. When using it, this plug is great for heavy - duty devices like amps and electric guitars. Just insert it into the appropriate port. As for maintenance, keep it dry and away from moisture. If it gets dirty, you can use a dry cloth to gently wipe it. Avoid using harsh chemicals as they may damage the metal and the spring. Also, be careful not to bend the spring too much as it's there to relieve strain and keep the connection good.
