The configuration I've been playing around with is a chambered, Alder body with a carved spruce top. A friend of mine took it for it's inaugural real world test ride over the weekend and we received quite a few compliments on how much bite his tone had, but it stayed very even and clear all over the place without ever getting brittle. None of this was any surprise. It's kind of what you'd expect to get from that combination of wood in that configuration. I'm making up a batch with some different body woods too...some laminations perhaps...certainly one from Khaya (i.e. African Mahogany). Maybe Sapele? Maybe Walnut? All three of those are acoustic side/back woods. I may make one with a figured maple top because I have the wood here, but I've tried that before and it completely ruined what I was trying to achieve, leaving something else cool in it's place. Just not what I wanted but cool nonetheless.
I wish I had a piece of Indian Rosewood big enough to make a body out of
Maybe I can laminate together a bunch of fingerboards? 
I suppose I could order some...
