John Bellar played a Wechter Scheerhorn resonator guitar and a custom Weissenborn guitar crafted by Tim Scheerhorn. Ron Neilson played a custom Dave King Weissenborn guitar and a Celtic Cross baritone Weissenborn guitar. The baritone Weissenborn is a 30" scale instrument and all other guitars are normal 25" scale. The unique combination of the differently scaled instruments combined in many alternate (and dissimilar) tunings on nearly all the duo's music arrangements helps create the signature sound. Ron uses D'Adarrio strings and John uses GHS Strings. Tim Scheerhorn is a custom luthier based in Dickson, TN Celtic Cross Instruments luthier, Neil Russell, is based in Vancouver, British Columbia. Luthier Dave King is based in Reading, England.
