Dunlop just sent me some new sets of their stainless flats DBFS40100 or 40-100 because I've had a run of G string intonation problems with their 45-105 flats.
I put one set on a Jazz bass last night. These strings intonate okay but they seem to pop-creak more than usual as they're tuned to pitch. By this I mean, more than what I typically expect even from brand new strings.
I already thought the bad G strings from the prior 45-105 sets popped-creaked in this manner more than usual. Now with this 40-100 set, the both G and D seem to pop or creak even more. I think this is something that's familiar to most, particularly with new strings, but this seems more than typical to me.
Perhaps the strings are slipping more than usual on the tuning posts, I don't know. The nut slots aren't too tight because they already slotted for 45, 65, 85, 105 strings.
I'm not sure how concerned I ought to be, sensitive to the fact that I'd already had problems with the same Dunlop flats in 45-105.
