brightening a Yamaha

[Andrew and Rebeca Anderson]

Alan,
You can start by making sure the hammers fit the strings well and 
then polishing with high (400-600 grit) grit paper.  If that isn't 
enough ironing will get more clang.  If that isn't quite the 
direction he wants, try papering everything off and then spraying the 
hammer tips with shellac (lightly) and see how he likes that.  You 
can brush it off if he doesn't and it breaks up as the hammer plays 
in so overshooting your voicing goal long-term is less of an issue.
