I have a pair of USD wave guides. they are missing the horns and one is missing the piece that connects to the guide and the horn. Not looking to get a hole lot for them. Would be prefect for someone who has blown there guides. Looking to get about $35.00 shipped, with insurance. Paypal is accept, however if paying via a credit card please add 2% to the total. I'm willing to spilt the charge with the buyer. Let me know if you want pictures. Picture is in avatar
