| hello all.
| 
| Maybe the same metallurgist can explain why doing so 
| (twisting bass strings that much) the inharmonicity increases 
| drastically.
| Hellerbass, Germany recommends twisting no more than 3/4 of a 
| whole turn, just to put the pin in right position.
| 
| Best regards.

This has long been my practice regardless of what the string winder says. So far
I've had very few buzzes.

I have no experience with measuring inharmonicity after twisting. One more thing
to add to my list of things to look into Real Soon Now.
