First of all sorry if this is the wrong place. I wasn't sure of the "customizing section".
It's more like fixing.

OK my guitar is a Maison C833C. It's an nylon acoustic guitar. The 3rd string has this ugly rattle to it, kinda makes it sound like its plugged in and distorted (weird as its not electric of electric-acoustic.) It only makes the rattle when open, and only when you play it with your finger hard, never with a pick. If you pinch the 4th tuning peg, it stops. It sounds whenever u try to play and I need help!

Please help me. Im clueless
Thank you for your help.
tighten the tuning pegs. that note played by the third string is probably the resonant frequency of the tuning peg, causing it to rattle.
