If people are worried about the ecological considerations of chopping down trees raised by josepp, they should perhaps also consider the amount of electricity required to smelt the aluminium required in order to manufacture resonator cones!

I don't recall ever having seen a non "book matched" top or back on a guitar - they are pretty much standard and everyone knows them as "solid tops".

PS as the owner of half a dozen or so solid topped guitars slightly fewer mandolins and a couple of resonators, I have no axe to grind in the matter!
