I've scoured the internet, and although there are many 7 string archtop guitars with trapeze tailpieces out there, I cannot find a replacement trapeze tailpiece for a 7 string guitar anywhere! Here's a 6 string example. Anyone know where I can find this for a 7? I should note, I have been able to find some extremely expensive carved ebony 7 string trapezes, but I'm not looking to spend $200 on a tailpiece. Thanks.
