Thanks for the thoughts Richard.

In this case, I am not entirely convinced at this point that I am looking at
a case of loose bridge pins.

Reseating the pins? I did not push/tap the pins. I did however seat the
strings in every gently way I could think of.

I have read all from Mr. Ron Bridge, but I'm not sure exactly what you are
referring to regarding "seating business". Could you refresh my memory
please?

Have you noticed that Ron has not provided input on my recent post regarding
how many hours one would charge a client to recap a bass bridge (I did
request that no bionic bridge dudes need reply!)?  ;-)
