Hollow body for bass VI neck
I've picked up a Danelectro 30in baritone neck that I plan to use in a Bass VI style build, tuned E to E, or D to D. I started to modify an old Prestige copy of a Burns Bison bass (recut the pocket, moved the bridge back) but I'm just not feeling it. Maybe too easy, whatever, I'm not going to continue.
I've got a yearning, though, for the feeling I had when my hollow Gretsch guitar would start to feed back, like it was pumping air. And I'd like to have a Bigsby again.
So I'm going to build a chambered body for the Bass VI. But I wonder if a deep, chambered body is going to feel like a traditionally built hollow body feels at high volume.
What body air volume should I be shooting for? Is there a point in going big, like jazz box big, to get the internal volume? I'd like to use a maple top and floating bridge, but what would you recommend for the back? Mahogany? Home Depot pine? Would I even hear a difference?
Thanks for any help you can offer. I've only had one chambered bass, a Spectorcore, and it didn't seem any more "alive" than a solid bass, just lighter!
