First published as a folk music magazine in 1971 by Michael I. Holmes before going online in 1997, Mugwumps is a no-frills, highly informative site that’s packed with well-written articles, detailed photographs, and historical ads of old instruments and parts. The focus of the site is antique and vintage banjos and mandolins, but there are also resources here for those interested in guitars. More than 1,800 instrument makers from before the Civil War until World War II are cataloged; headstocks of un-named banjos are identified; and the gallery of banjo tailpieces will help you tell the difference between an 1887 A. G. Wood and a 1929 Oettinger.
