This all-Koa JB-15-WRX is speculative. I chose all-Koa because I haven't made one for a few years, and because I have several homeless Koa flitch sets. Although my website says I don't offer the JB package or even a cutaway as options for my WRX, I just made that up. This guitar will be relatively affordable, and not available to retail as there is too little margin.
