The Pramberger line of pianos is named after the late Joseph Pramberger, a former engineer and piano designer at Steinway. While his name lives on, his piano designs have been replaced with modern designs from the parent company, Samick. The three lines of pianos are divided into Legacy, Signature and Platinum. They differentiate in that the Legacy line has laminated spruce soundboards while the Signature and Platinum lines have Bolduc solid spruce soundboards. The Platinum series also is fitted with either Abel or Renner hammers.
