Smash
Hack
I am curious to see what you find. I can see how the neck could matter for sustain, but I have always been skeptical about body. I have played all kinds of guitars, though, and never had an issue with sustain...so at the end of the day, I just think about looks and feel.From what I recall they measured and ruled that out for the body too, and attributed it to other elements. But I'm not here to argue right now (once I get a laser vibrometry set-up that could change, though...), just wanted to offer up that I think there isn't any issue with the current wood selection.
Nitro feels amazing, especially the neck. I have never been bothered by a fretboard being ebony or rosewood, but I have never tried maple.
