[CAUT] RE : Quick fix Duplex was duplex

[Jeannie Grassi]

Hi Marcel,
I've been having some success by using Scott Jones'  Pitchlock TCouplers.
They weren't originally designed for that purpose, but have turned out to
help, or at least improve the situation, a good deal of the time.  I have
found that using bushing cloth or string deadens the higher partials too
much.  And I've made a terrible mess trying to use glue.  This is quick and
easy (once you get the knack of manipulating the little things) and doesn't
seem to affect the tone as adversely as some of the other remedies.

OK guys,

This is mostly something that should be looked at and taken care of with
restringing. Now, what do you do when the buzzing is getting in the way
of a clean good sound and you're just there for the tuning. Have any of
you found reasonable fix for this buzzing?

My first tentative is to move the string side to side on the capo and
sometimes on the front duplex as well. If no change happens (which is
rare) or the change is not enough, I now try the "pitch lock" on 2 of
the 3 strings (I try to find which one is the worst to start with). Now,
if this doesn't work AND the piano is NOT in a concert hall, I will on
occasion mute the whole thing. For concert hall pianos, I will mute the
whole front duplex (temperament felt)if it disturbs my tuning and then I
will remove my mute.

Any other ideas ???
