I decided on a B30 for my Electro Double Jet, but am having an issue mounting it. The import model Bigsbys have that little extra block of metal right in front of the hinge that raises it up off the body for mounting, which I imagine is there to make mounting easier in terms of knowing how high/low to raise the end of it. I have placed my B30 on the guitar, and the 'headstock' end of the Bigsby wobbles--the two areas with the felt do not come into contact with the body at the same time due to the carve of the top. What are my options here? Should I just add some sort of felt under the lowest part of the end that is not touching (which is under the axle/bar that holds the strings)? If so what materials would you suggest? Thanks for any suggestions!
