Hi, A recent thread turned me on to Birdsong's Cortobass, and I'm likely to get one. But someone in that thread thought the Cortobass was overpriced and that one could do better going to a different custom builder. So, among custom makers, who does short-scale or medium-scale basses with a better bang per buck than Birdsong? P.S. I am not asking what you think of short-scale basses, and I am not asking about production basses like Epiphone, Kubicki, etc. however nice they may be. Thanks!
