Let me preface by saying I have only installed one other set of flatwounds(D'ad Chome XL) on my Epiphone EB3 and it went fine, no issues. And after I returned the EB3, I took the strings, cut them down, pinched the ends, and put them on my Bronco without any problem.
Now, I got some webstrings flats for my new artcore agb140 longscale. I go to put on the E, cut a little off the end---the whole damn thing starts unraveling. I didnt clip into the fattest taper, there was no need to even go that far in. I tried to salvage it, push the winds together and put it on, but once it was on, it unraveled near the nut and farted terribly whenever played.
Aside from that these are covered in the nastiest black manunfacturing dust... I expect a little, but after one string my hands are black. These strings also don't feel great. Kind of surprised, because I find that for the price, their rounds and guitar strings are VERY acceptable.
Did I do something wrong? Is there something I should have done? Pinched the end? Or did I just get a dud set?
