Recently I was reading some material on the web about old English basses. One thing that I found interesting was that some of the great basses were such exact copies of the italian models that they could hardly be told apart. This leads me to the question; How are basses (and other instruments) truly identified? Because I know many of them are made to be as identical as possible to allready existing instruments, so what are the details that separate them from the real thing? Obviously labels mean nothing, because I've seen really expensive, big name instruments sell at auction with no label. And I would think a maker would try to leave no detail different from the original. So how does anyone know which ones are the real deal?
