Re: Check out this "tonewood" statement . . .
That would be like saying a tin can sounds like a brass bell. EVERYTHING has a specific tone. Tonewoods are called tone woods for a reason. A 4 foot plank of wood cut into individual identical guitar bodies may not sound identical due to differences in grain, pores, density, etc. I once had a Zola flamed Maple capped Honduran Mahogany strat/soloist body that I couldn't make sound good no matter what bridge, pickup or electronics I installed. The body had a real Fender strat maple neck.
If you add mass or take it away, that will have an effect on overall tone. Lighter or heavier, metal or plastic. Everything affects the overall tone. Black Korina does not sound like Swamp Ash, Mahogany does not sound like Poplar, Alder does not sound like Purple Heart.
