See the gear DJ Ashba, Richard Fortus, Ron "Bumblefoot" Thal, and Tommy Stinson used on tour in 2011.
"A Vigier signature artist, Thal uses a G.V. Wood 6-string on the road with GNR in addition to this custom Vigier doubleneck. The fretless neck is tuned to dropped-D. The bands on the fretboard near the nut are used to mute open strings during tapping segments."
