Wayne, just sent you a note earlier, missed this one, glad you like the harness, i have two, one set up for the tenor and one set up for my alto, great neck savers.
Yup had the same problem with the bundy 2, on low D, i actually fixed it by taking out the pad and replacing it with a new one, that key sticks up enough so you can take the old pad out and put in another one without removing the key. I experimented with using two sided alien tape to hold it in place works great, cut it to fit the back of the pad and slipped it in, and you can remove it if necessary. Low D plays well again. Happy New year to you also.
