Would this technique be worth considering for older instruments? For example: an 80-year-old compression crowned instrument whose = soundboard is visually=20 in good condition but flat in the mid-treble, resulting in short sustain = in that range. On the one hand, the SB might already be crushed and "dead." On the other hand, if new built-up ribs could provide sufficient = springiness by themselves, the soundboard would only have to serve as a diaphragm, so perhaps even = a dead SB would do. Your thoughts? JCA ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
