Canada?  Cheesy

Sorry, couldn't resist that. 

If there are no mail-order places in the US supplying it (there must be, surely?) SLEC in the UK (http://www.slecuk.com) have stock.

Would Bass wood available locally at say Michael's in the US be a good substitute?

Depends on what it's for. For leading edge reinforcement, Basswood is preferred imo. For fuselages, Spruce or very hard balsa is preferred over Basswood. But I haven't used or bought spruce in so long since we started using carbon fiber tubes for CLG fuselages.

Steinway Piano used to get their pick out of the best ten percent harvested every year from a forest in BC. Then they'd ship their selection to the factory in New York, season it for a couple of years, use the best ten percent of that for soundboards, and discard the rest. I was able to scrounge a couple of 4x4's, 6 feet long from the discards. It was first class lumber. You couldn't buy anything close on the open market.

Broken acoustic guitar tops? Ask your favorite luthier.

If you don't want to mail order, a sandwich of wood veneer/balsa/veneer, or a box of veneer, would probably outperform spruce. Depending on the veneer, it might have to be slightly thicker, but not heavier. Douglas fir might be the best choice, but other woods could still outperform spruce if done as a box.

Spruce isn't just spruce. There are many varieties. I suspect a slice from a close grained spruce (not pine, not fir) 2X4 would be fine, if not QUITE as good as Sitka spruce.

In a number of places in my area, there are reeds which would make fine, if weird looking CLG fuselages. Also, in the nearby park there's a pile of discarded bamboo cut from an overly large stand of it.
