I agree with sound. trust, me if it doesnt sound good, its off to the wood burner. When I say quality, i am talking about how well its built, the type of glue used, how well the soundboard is put in. I have had calls that sound great then got wet and the surfaces popped right out of them. also soundboards have come loose on me. if a call sounds great but isnt also built just as great as it sounds, i wont buy it, nor will I sell it.
