[CAUT] Riblets

[Ed Sutton]

The August Journal has a feature article on voicing the soundboard with 
riblets and/or weights.  Lots of details.
The November issue has a small update.
It's easy to attach a riblet or a weight to a strung and tuned piano, and 
you can hear the effect immediately.
The August issue is the one with a riblet on the cover.
We felt that these methods of dealing with impedence problems constitute 
some of the best tools in our knowledge kit.
We put the riblet picture on the cover to catch people's attention and make 
it easy to find the issue latter.
