[CAUT] False Beats and George Winston

[RicB]

I repeat,

Loosening the (tuning) pin.. i.e. takeing down the tension of the string 
before taping a pin takes this whole friction argument out of the 
picture. And there is good reason to believe that movement of the pin 
can affect the overall massyness the termination as a whole presents to 
the string.  For that matter, tho I know of no study one way or the 
other that addresses the specifics of bottoming the pin out... it is 
certainly feasable to think that doing so could potentially influence 
the condition.

It is an error to think that it is the pin itself that is the culprit 
here in bridge related single string beats. It is the overall 
springyness/massyness condition of the entire termination that is the 
root cause. The pin is not the simple and single support of the string 
as in the pendulum analogy much of this reasoning seems based on. The 
picture is more complicated then that.

I would also point out, that the net result of downwards pressure on the 
bridge by the string from tapping as described below assumes that the 
pin is already holding the string quite solidly in contact with the 
bridge. This is clearly not always the case. It is very much possible to 
tap the pin with tension on the string and end up with no net pressure 
on the bridge surface itself.  That said... I would let tension down on 
the string every time before taping a bridge pin to be on the safe side.

    There's about 25 lbs of side bearing on a pin at a 10° offset
    angle. That makes about 14lb of friction between the string
    and the pin. So tapping the pin down is the rough equivalent
    of gently seating the string with a 14lb hammer. Whether the
    pin is at the bottom of the hole or not makes no difference
    acoustically, though that's the illusion and everyone's
    conclusion when bottoming pins clears up a beat. When you seat
    the pin, you're just seating the string once removed, and
    still haven't addressed the cause.
