Well, I'm laying out the hollow pockets on my first bass. It's gonna be a semi-hollow body. And I got this idea... Instead of having one big pocket, why not have a bunch of drill holes, very close together, so that there are columns of wood left behind but most is removed? This would allow the top and back to be much thinner than my planned 1/4" but still just as strong. Or the leftover wood could create walls, with air passages in between. So, the body would be very rigid, with lots of surface area to move air around inside, but still very light and strong. from what I know this should produce a different tone than a normal hollowbody. But has it ever been tried before? And if so, does it sound any good?
