Roundwound string ID request...

[mikewalker]

Does anybody recognize these, perchance?

They are 45-100 set... I think maybe SS, but I could easily be wrong. Slightly rough feeling. I don't recall ever seeing these yellow/gold silks before!
No silks on the ball ends (chrome colored ball ends)

If they came stock on your Willcox, they’re Dean Markley SR2000 Steels. That’s what Chris was using before moving over to GHS Contact Core Super Steels.
