BAM! That's it, right there. I have a WGD with an awesome-looking one-piece BK body. But the thing weighs twice as much as an old Les Paul Custom. I never play it because it is so freakin' heavy. I actually ordered another body made of swamp ash with a camphor burl top. I just need time to move the neck over, install the hardware, and wire it. The new body is about half the weight of the old one.
It would be awesome if Warmoth offered the WGD with chambering, but, alas...
