Ended up deciding to go for cedar and mahogany, after all. It's the cheaper option, I don't currently have a solid-body hog guitar, and if it goes well I'll definitely be looking to this guy for more work.
As a side note, I got the original Washburn playing again and discovered it's a bit older than I thought. I don't know where I got the idea that it was 1918-1920. but after doing a little research it seems it's actually
this model (stamp is identical), which makes it 1890s or earlier.
Used to be my dad's, and the top is warped (had medium strings on it for at least 40 years). But even with a lighter gauge it has a great sound. Intonation is pretty much spot-on too, though you wouldn't think so to look at it.
