Probably an ignorant-sounding question: Can anyone quantify, or in some way describe the differences in sound, [playability, or something] between a flatback bass and one that has a carved, arched back? I am not a player, but am building a bass, and was really torn about whether to build one or the other. I have built violins and violas, and have repaired celli and basses, but ALL had the carved backs, so flatback just doesn't look right, to me. But I know they are fine, and that many professional players use them. If there is a consistent difference, I'd like to know how it manifests itself. I know an archtop guitar and a regular guitar don't sound quite the same...but I could not explain the difference.
