If you order a SingleCut bass there is the choice of having it headless or with a headstock. Yan wanted the headstock. He also wanted a lightweight body so alder was used for the 'wings' each side of the through neck which was made from laminates of hard and figured maple with mahogany stringers. Carbon fibre rods are each side of the two way trussrods.The top is Irish pipy oak which comes with lots of holes in it! The holes were filled with epoxy resin coloured to contrast with the natural wood. Makes for interesting figure. When it came to the electronics Yan wanted the best - a combination of Larkin/Armstrong humbuckers processed through a John East Pre which makes it incredibly versatile. The fingerboard on the 34"scale neck is rosewood and the frets are Dunlop 6110.
