Great importance is attached to the use of only top quality materials and a high standard of workmanship. This begins with the manufacture of the backpost, during which finger-jointed solid spruce and Delignit are used to form the backpost with glue-mounted Delignit pin block. After all, it is the backpost with bearing that forms the basis for the exact conditions of camber and tension in the soundboard. And the secret of that unmistakable, transparent SEILER sound is to be found here, in SEILER’s patented membrator soundboard. This is why only narrow-ringed, mountain spruce is used – selected by experienced wood experts and subjected to a special drying process. And even if these technical details are scarcely visible to SEILER customers across the globe, they are nevertheless audible. A single note is all that is required and it’s “love at first sound”.
