So I’ve built 4 cedar boo bows. One fretted, the other 3 have been fine. My advice to anyone thinking of the combo is to make sure you thin the boo a lot - razor edge on the edge of the boo or as close as you feel comfortable. Make the boo narrower than the belly (trap the back), and make sure you’ve got a good glue line. It can be a great combo but I don’t feel it’s a forgiving combo either.
