Greetings to ALL. tonequester here. I am re-doing my first, and LONG post. Concerning an electric guitar. Strings resonate at say, 800Hz. Wooden neck and body have their own resonant frequency, so I am told. No two guitars resonate at the same frequency, as no two, complex, combinations of the same wood could possibly be exactly the same physically. Will there occur any phase cancellation between the strings 800Hz vibration, and the resonance of the neck/body combination ? If not, why does adding considerable mass to the headstock(top of neck) or to the guitar's body, increase volume and sustain, if not by phase cancellation ? There is much hype and sales pitch involved in this regard for too long. I'm out for the truth. Example : Nitrocellulose finish makes for good tone because it lets the wood breath, and resonate. My Answer : Nitro plastic coats the wood. How can it breath. Hey ! Wood doesn't breath anyway, IT'S DEAD ! All PHYSICS based comments are very welcome, and appreciated. Best Regards from tonequester.
