I just got my copy of Traeger's bass repair book. As I was perusing it last night, I found an interesting section in which he claims that there is a notable difference in sound between violin-cornered and gamba shapes. My understanding of what he states is as follows: Violin corners allow more flexibility in the top and allow the ribs to move more, creating a "darker" sound (more low frequencies, fewer high frequencies). Gamba corners allow less felxibility in the top (create more rigidity?), and therefore move the ribs less, creating a "brighter" sound (fewer low frequencies, more high frequencies). As such, he recommends violin-cornered basses for orchestral (arco) work and gamba-cornered basses for jazz (pizz.). From everything I've seen and read (though I haven't heard or done A/B comparisons), most people think that shape is more cosmetic than anything. Traeger indicates that this is not true. I have not been able to find anything in the archives that indicates anything other than the idea that shape does not affect sound. Does anyone have any experience with or thoughts about this? If Traeger is right, where do Busetto-cornered basses fit into this? What would be the impact of this on less-expensive basses (hybrid or all ply)? Would gamba corners help create more high end in an otherwise tubby-sounding all-plywood bass? Or conversely, would violin corners help to "mellow out" the tone (counteract the stiffness of laminate sides?) on a plywood or hybrid bass? Of course, individual basses, manufacturers, materials, etc. will affect the sound of each bass -- but can some generalizations about shape/sound actually be made in the way that Traeger has?
