I recently bought a P-90 model online, mistakenly listed as the M-75 hollow body. I almost returned it, but they offered me a smallish refund and I loved the way it sounded and played -- pickups sound GREAT and the neck profile fits my hands perfectly. So despite the fact I'd wanted the ultra-light hollow version, I kept it. Now I'm back to wishing I had the M-75. But wondering what the differences might be aside from the hollow (vs. chambered) body. I'd hate to sell this and then buy a guitar I like less. Not having luck finding this info online.
