Doing business with Banjo Studio was a joy. Will most certainly be purchasing a mahogany OM down the road. As far as the Cocobolo is concerned, it's an amazing acoustic. For the OM size it packs a lot of punch. Very clear and crisp highs and mids with a lot of bass. I haven't played much acoustic in the last two years, so it's making me earn my keep, yet very rewarding. I'm sure down the road it will open up a bit with a little more warmth. I realize that mortise and tenon neck joints take longer than a glued dovetail. But like they say you better like the way an acoustic sounds out of the box, and this one shines. As far as the torrefied sitka top goes it's really hard to say. I have nothing to compare it to in terms of tone. So, I suppose the jury is out as to whether or not it's worth the extra cost. But it sure looks great!!!
