Yeah, there were about ten guitars and basses I can think of that had the Bigsby installed at the factory. Nearly all of them were later removed. I thought all the basses had them removed until I saw the Sotheby's auction. That's gotta be the last one out there.
Matt's more recent drawing is with the upper body half compressed and a little smaller. The original idea of the shape was to make the upper non-cutaway side look like the bottom of the Small Standard body shape.
Both Matt and I thought the back of this design looks more amazing than the front. Hey, maybe we should do something where we incorporate the scooped out look of the back to the upper body half, a little more sculptured perhaps?
