Can someone please tell me how a hollow bodied bass sounds different than a solid body? Take a look at this: Wolfehollow's Bass ....now did that hollowing out change the sound or just lighten up the weight? And does a hollowbody have to have sound holes? I'm kind of thinking that it does because in a worst case scenario, won't heat (say from being in the trunk or in direct sunlight or under lights period) cause the inside cavity to expand? Or am I being too scientific? I like the idea of saving on weight, so that's why I'm interested, but when I think about basses that I like, they're all solid.....MTD, Ken Smith, Lakland, etc. If I'm about to commission a 3 or 4 thousand dollar project that I want to really be a keeper, I want to get it right. I don't think I'm going to be able to audition a hollow body anytime soon to draw my own conclusion, so I'm querying the abundance of knowledge here at TB.
