Ever the eagle eye, Tom... Before eBay came along I reckon you spent at least some of your time at festivals explaining to folks that they didn't in fact get the deal of the century, and pointing out why their awesome new Gibson Mandolin is perhaps not as awesome or as Gibson as they thought.
Keep 'em coming.
Hereby & forthwith, any instrument with an odd number of strings shall be considered broken. With regard to mix levels, usually the best approach is treating the mandolin the same as a cowbell.
