Re: Concerning tone wood in solid bodies:
I think Mahogany and Koa ( no direct experience with Korina but probably very good to great as well) will be great choices .
I've had a lot of experience with Koa on 3 different guitars.
It's like Mahogany with a wider bandwidth - so it's fat and a little livelier than Mahogany with humbuckers but with single coils it gets a bit twangy and almost as bright as Alder with a bit more bottom end.
Years ago I had a factory passive H-S-H Koa Mockingbird that looked like a Metal Machine but it was actually with a Duncan 59 a stack and a JB in the bridge a warm almost vintage sounding guitar. The neck 59 sounded pretty close to Carlton's lead tone and still was warm in single coil. My current Carvin Koa Bolt is like a very fat and resonant warm Strat very loud unplugged, lots of sustain- does the FATTER sides of Strat very well and beyond( NOT the clucky thin stuff so well).With vintage Strat Pickups would still be fat but very Stratlike then.
So think of Koa as Mahogany on the bottom end and almost Alder on top end or like a fat but clearer Mahogany.
If the Walnut top is more than 1/8 " thick I'd use Mahogany for the bottom piece.
If you use Koa or Korina ( which I've heard great things about, like a combination of Mahogany and Ash-maybe livelier than Koa) - I'd think about NOT using the Walnut top 'cause you'll get more of the cool resonance of the woods without the top. And Korina and Koa are clearer than Mahogany and don't need a top for clarity and focus like Mahogany sometimes does.
These are are my opinions NOT fact, so feel free to disagree and I'd like to hear from Korina owners, but I know from experience that Koa is usually very resonant and I've heard Korina is also- so why put a top on it ?
Either way( top or not ) I think Mahogany ,Koa or Korina( maybe black Korina ) will give you more tone to work with than Alder, and a fuller unplugged sound- always a good sign.
There are people who say the wood doesn't matter- that it's 99% pickups- but most guys who make pickups say the wood DOES MATTER.
