More classic false beat tricks

Hey there Joe

Works for both slow and fast beating false beats... tho funny thing is
when dealing with a rapid twitter as you call it, its not so much as the
beat disappears entirely as it is it quites it down very much. Doesnt
seem to effect the speed of the beat.  With slow false beats they seem
to just go away.  I'm not really sure whats exactly happening here, but
clearly one is adding to the strings speaking length when applying CA,
some oil or protek as described below.   Where as a screwdriver coupled
to the bridge pin will slow down the false beat with increased pressure
until it stops.... and then if you increase pressure further start to
appear again and gain speed with more and more pressure.... adding to
the string as mentioned below does not seem to affect the speed of the
false beat, but rather somehow either damps it or alleviates some
condition in the string that contributes to the false beat. The pitch
drop may be related...or just another affect.

How any of this would affect the back scale I dont know... what got you
thinking about that ?  I have tried of course applying to various
lengths... but it seems the speaking length is the only one where any
noticeable affect results.

Cheers

        Hi Richard,
        Interisting. My thought would be that you have masked the load
        on the string
        and the thin spot that is deviding the string into unequal
        parts. Or helping
        to stop the back scale from ringing.
        How fast was the false beat/ A slow roll or a rapid twitter or
        helped in
        both cases?
