My son is going into high school next year and they recommend that he get a "step up" horn. They have 2 approved instuments for our band program but I am in the dark about all this so I need players opinions between these 2 instruments before we pay all this money. The 2 are a Conn 88H and a Bach 42-BO Open Wrap. Can anyone help me? I did try to research them but of course everyone is trying to sell theirs as the best.
