I personally would be inclined to do a mahogany body, and maple neck with rosewood fretboard. But if you dig the tone of those two Swans, you may want to do one of the ash bodies. I'm not sure if Tommy can get the redwood, though.

I bet mahogany over ash would be cool. You'd have the big highs and lows of ash, but a little of the mahogany mids thrown in.

What neck woods are you considering? They play a large role in tone too. As well as pickups and bridge choice...
