DELIGNIT/DEHONIT PINBLOCK Delignit pinblocks from West Germany incorporate twenty-nine plies of quarter-sawn high quality beech. The plies are permanently bonded with hot-curing phenolic resin glue to provide superior age and "wear" characteristics over maple. The extremely high pressures used in the gluing process produces very thin glue lines and increases the density of the wood. It is virtually impossible for reparations or delamination to take place even when soaked in water. The Delignit pinblock provides superior tuning stability throughout the life of the piano and is the pinblock material used in the world's finest European grands.   Dehonit materials are similar to delignit.  Both materials are used in premium musical instruments including Perzina and other world class pianos.
