Hi Forum. I’m considering getting a C-extension, and I have 2 questions that I need help with. Hopefully this is the right place for these questions. First of all, I’m wondering if there is a significant advantage to having a C-extension that requires drilling a hole in the scroll to install over the C-extensions that manage to route the string around the scroll, thus requiring no drilling? Anyone have any experience/info about this? Secondly, I know that extensions are always custom made, but is there any resale value for a used extension? Maybe the extension can be made to fit another bass? Thank you for your help!
