false beats from??

Hi Mike.

I have to admit I am beginning to question the whole <<understanding>> 
of false beats that has been circulating the past few years, ie 
attributing false beats to loose pins.  To begin with... there are 
simply to many exceptions to the rule and yours is just another of many 
such stories.  Secondly... its all seemingly based on the fact that in 
some situations we can let some CA glue, lacquer, or other such 
substance soak into the bridge pin holes and it helps.  Or that we 
notice that also in some instances you can add some mass and/or tension 
to the pin via a screwdriver or some other device and that helps... 
sometimes.  There is no real science behind any of this... nothing to 
show for sure whats happening.  Heck for all we really know there may be 
some entirely unthought of cause/effect relationship at work here.  The 
coupling devices made available a year or so back should point in other 
directions as well.   To many times you can eliminate this <<cause>> 
without eliminating the effect.

In short... I dont think I buy the loose pin explaination at all.  
Perhaps it is just one of several potential supporting events at best.

Cheers

Interesting. I had a similar "false beat day" yesterday. First was a old
Blasius upright that had apparently been restrung and pinned 2 years
ago, false beats like you wouldn't believe and the pins are tight as
hell, actually broke a tuning hammer tip last time I tuned it. Nothing
worked on the beats, bridge looked great,  seating, pressing on the
offending strings bridge pin with a screwdriver didn't show any
improvement, slid strings to the side a bit to try a different v-bar
termination, then finally rubbed the length of the strings with a brass
rod and that helped ever so slightly, finally had to give up for now as
appointments were backing up. Next was a 70's Yamaha console, I thought
"thank God, something I can tune and feel good about" as my shoulder was
getting sore, this was even worse, out with the action, same scenario,
walked away not feeling good again though it did sound decent.

Some days you wonder...
