Goncola Alves isn't a wood used here that I know of. Weng? doesn't work well with our finish (that mineral deposit can look like a crystal or a piece of dirt). Tulipwood has always been difficult to procure in wide widths (if we only made 3 wide guitars!), and of course Koa by definition is scarce, but we still can source excellent material, and have a nice collection here.
Bocate is funny - the price has escalated to the point that it can't be offered as a standard wood any longer. It is harder to source nice looking material in wide widths. Of course I can get wide veneer all day long!
There are many new woods we're offering. I'm loving the Flame Redwood and Burl Redwood additions. Jarrah Burl has only been offered for a few years now. True, there are very limited quantities available of Chocolate Quilted Maple and Pale Moon Ebony.
We keep trying different things, there's more than 100,000 species of wood to explore and enjoy.
