Hello folks and fellow Roscoe users.
If that doesn't help, please PM, e-mail (info@roscoeguitars.com) or call (336-274-8810) me, and I'll be happy to help you trouble shoot the issue.
FYI, I'm still running on the same set of DuraCells in my fretless that were installed at the time of completion, in January of 2006.
