Voicing Down a Yamaha U1

[Isaac sur Noos]

If a Yamaha is harsh that is because the felt is too hard at the top
and underneath, sugarcoating is the eventual final step in my
procedure (rarely necessary)
I prefer to needle with force not too far from the crown, as at the
same time I have energy back and the result last longer.
If I want to open the tone I knock strong on the base of the external
shoulder with the back of the voicing tool. If IO knew how to tap on
the inside I could do that as well (and even reverently in fact)

The action is installed on wooden blocks , horizontal, on a table or
even the floor; a firm wood support under the heads.

The attack noise is mostly coming from the inside shoulder (the bottom
shoulder when the action is standing). This part may be firm but not
so hard and it harden more that the other side.

On the external part of the hammer I think more resiliency and rebound
while needling (often very little needling is due there, or the energy
=disappear.

And of course grooves may be acceptable to begin with.

If that is not  enough a half liter of tea or coffee may be spilled on
the heads, sometime somebody have yet done that inadvertently so you
don't need to do it yourself.

Some day I will try a drop of water and a hot iron, but on the
underneath of the shoulders, to avoid the softening of the external
layer too much.

zats all folks !
