What's the deal with Tyrolean Basses. I keep hearing and reading about them but don't know much about them. Do these basses resemble German, English, Italian, or French basses. Do they tend to be bigger, 7/8ths or are they more on the smaller end? Most importantly how do they sound and are they readilly available or are they hard to find and expensive. Also I know each bass is different but I've heard Tyrolean basses tend to have longer string lengths any truth to that.
