Offset sound hole lid making

I made off-set sound hole lids. Those lids are designed for stage performances with other instruments such as bass, drams, and vocals. In stage performance, feedback related oscillation issues are quite common. This lid is able to minimize the issue, because the acoustic chamber (guitar body) reacts much less responsible with no sound hole. With this optional lid, the Jazz Nylon model improved significantly for set-up difficulty for stage performances.
