Guitar players unable to eliminate unwanted overtones and harmonic frequencies that ruin their sound

Guitarists struggle with uncontrolled overtones and harmonic resonances that muddy their tone and undermine their playing quality, especially during recording or live performance. Current solutions like trial-and-error technique adjustments, expensive equipment upgrades, or vague online advice fail to provide systematic, actionable methods to diagnose and eliminate specific harmonic problems. Players waste hours experimenting without understanding the root cause of their tonal issues.
