My previous Catalpa experience (2 guitars and an all-Catalpa Uke) was indeed harvested by myself in Mill Valley, California. This Catalpa is a much stronger Timber, though still quite light in weight compared to Mahogany (for instance). I got this wood from "otterhound", which is the posting handle of Richard Eyman, who works out of Manheim, PA. I imagine it grew near there. He had a good size pile of it on the table at the Woodstock event this year, and surely there is plenty more where this came from. His prices are lower than seems reasonable to me, and this wood works easily, bends easily, finishes easily, and sounds great. If that's not a recommendation I'll be happy to make one: The all Catalpa (back/sides/top/neck) guitar I made was sold to a 4x customer of mine, and has been his #1 go to guitar for 2 full years now! He'll be a 5x customer soon, so I am working to dethrone "Blondie", as he calls "her".
Here's the bridge I expect to use on the Classical:
