I would think it would be hard to get wide enough pieces of pear wood to make book matched backs, though. I just haven't seen many pear trees with sufficient girth. Nice wood though.
I think that's probably very true. My pear trees in the back yard, are at least a hundred years old and big enough to maybe make lute ribs...one of the lutes with 31 ribs in the bowl.
I did pick up some nice flamed European Pear sets last summer that are plenty wide enough for full size classical two piece backs. But I'm told they are pretty rare as most places don't log fruit trees unless absolutely necessary or they came down due to natural reasons (wind, age...).
In my neighbourhood there are some very large Japanese Cherry and Plum trees that I'm waiting to come down. There will be some good two piece backs there...a little twisted maybe.
I've used some of the Oregon Walnut for a fair number of my instruments and I really like it. The shop smell great and it makes a nice sounding guitar to boot...but Maple is still king IMO.
