VERY unusual instrument. Very bright, very loud. 99% certain that this started life as a lapsteel guitar, and was at some point converted for Spanish-style play. So the fingerboard is very likely not original, of course, and neither are the Waverly tuners. Pickguard added many decades ago, too. But the owner is pretty darned sure everything else is. It’s old koa all around - top, back sides, everything. Mahogany neck. Sparky!
