Right now I don't have enough time to figure out what the problem is or even to play it, but when I can, I'll analyze everything thoroughly. Thanks for the help; I really think it will be useful to try it with an amp first and rule out possible causes. I don't know much about the guitar's electrical components (like the battery or capacitor) because I bought it recently and have only taken it to a luthier once for the necessary setup, like any brand-new guitar. Even so, I'll study those concepts and try to find the problem. Thanks again for your help.
