Using a hand-rubbed stain - rather than a sprayed paint finish - results in a unique look to each guitar. Further to this, Spruce and Mahogany have differing cellular structures, so there is natural variation in the way that the stain takes to each peice of tonewood. This stunning quirk of nature is especially noticeable on the Spruce top, as in some areas, the black stain will be absorbed more than others, creating an individual patina to each and every model: Some will be more uniform black, some will have more wood pattern visible.
