I posted this question in the Forum but seek specific input from experienced techs here:

Anyone ever seen blackend or somewhat discoloured bass strings on new grands?

What brands? How would this affect tone and longevity of the strings?

As a dealer'tech I know about the above but
seek others' opinion here.

Will have to give 'expert evidence' on this
matter, soon.

Thanks for all posters in advance!
