Features Fingerboard : Maple Inlays : Abalone Star Hardware Color : Gold Finish : Gloss Color : Classic Black Description Product Description The first Sky Guitar was built by master luthier Andy Demetriou in Brighton, England, in 1983. This one already had virtually all the typical features regarding the shape, but in other ways there was still quite a bit of room for improvement. Most Sky Guitars are made of alder, which is a preferred wood for the Strat. The present series uses mainly Bavarian alder. Some guitars come with quilted maple tops - very few with a flamed top. Most 7-string Sky Guitars are made of mahogany, and most of them feature a quilted maple-top - even those which don't show the pattern of the wood, like the Blue Infinity Sky, which is one of my recent preferred prototypes. Inside the neck there is a truss-rod, which can be adjusted into both directions by turning the screw, which is hidden under the little golden brass cover on the front of the headstock. All Sky Guitars come equipped with free-floating tremolo systems and don't have a locking mechanism. When the guitar is set up properly there will be no problem to keep the guitars in tune, even when using the whammy bar extensively.
