Check out this neat video from Jim Dunlop about their string manufacturing process. Very interesting stuff. And keep an eye out for top players like Zakk Wylde, Doug Aldrich (Whitesnake), Jason Hook and Zoltan Bathory (Five Finger Death Punch), Matt Heafy (Trivium) and Phil Demmel (Machine Head).
I gotta say, I’m very happy indeed with my Dunlop strings. I’m one of those dudes who likes to try every brand pretty regularly so I have a feel for what’s out there (go on, ask for my opinion about string brands some time when you have a week spare), but I come back to Dunlop strings probably more often than any other brand, and I swear by them on acoustic guitars especially. I can’t wait to check out the new Heavy Core 7 set.
