Using your Cort KX307MS - OPBK electric guitar is easy. First, tune it up using the Cort® Staggered Locking Tuners. Plug it into your amplifier and start playing. When you're done, unplug it safely. For maintenance, keep the guitar in a dry place. Wipe the strings after each use to prevent rust. You can use a soft cloth to clean the body and fretboard. Check the tuning machines regularly to make sure they're working well. When changing strings, use the D'Addario® EXL110 + NW059 strings recommended for this guitar. And always be careful when handling the guitar to avoid any damage.
