Next size larger bridge pins

[Joe & Penny Goss]

obert,
I think that also there might just be a connection between wire size and the
need for a sharper termination point.
The smaller the wire size the smaller the point.
Even perhaps too big might drive the inharmonisity higher.
Do the changes occur at wire size changes (when they are present)   ???
Just thinking do not know.Joe
