>I built an experimental piano once using a spruce soundboard, laminated to hold a small crown and used no ribs. Admitidly the bridge was of a different type and in a different position than standard, however, > >The tone was slightly hollow, the volume was down, but the sustain was incredible. Ihave seen many old (1800s) piano with seemingly no crown but still with a reasonably sound. > Tony, How thick was the panel, and how did the bridge configuration and position differ from 'standard'?
