So I just got my new classic-IV pro bird, plays like a dream though the set up is high, easily adjusted, so I ordered a warwick rockbag for buzzard/beast and they said it fits the thunderbird with it, but holy cow it's fooken huge. But it's well padded, got a neck/headstock strap and cushion in there with a hidden pocket, shoulder saving strap which is wide and nice. it's got 1.5inches allowance on the sides, and 2-3.5 inches at the bottom for your bird, my problem is I need a smaller one, why? cause I'm short (5'6) and the case is up to my nose.
