Everything's possible. But with electrics wood gets the backseat when it comes to tone. The more gain and fuzz you crank the the less wood tone you'll hear. I'm sure that the wood does contribute to tone, but with electrics not so much. In my opinion putting old growth wood into a guitar that would be played for heavy rock is a waste of time and money hehehehe. It's just luthier's salestalk to me. I'm sure many would disagree with me on this.
But a narra guitar would be so cool. We could chamber it for or make it thinner. Personally I would chamber it, I like my guitars thick ( or tall) and with the hollow body I'm making now when I tap the top it really sounds like a drum and it rings like a bell. Don't ask me how I did it, I don't know
But I bet will density and hardness it will blunt the tools used.
Ther's this company in muntinlupa called " ancestral building materials" Haven't been there, but their website says that they have old narra, molave and kamagong beams salvaged from old houses. If anyone from that area can check it out and report it to us, it would be a great help. How much and if they custom cut.
