Dave Fecca on SFT Screamers. Guitarist / Luthier and c-writer for All Things Strat Having past experience as a machinist, I first noticed how these strings were wound. They seem to be very sturdily wound, which is further reinforced near the ball end of string. Especially on the 4th, 5th, & 6th strings. It also became apparent that the 1st, 2nd, & 3rd strings have been made with a carefully wound ball end as well. When I put them on my guitar I noticed that they seemed to be pre-stretched. When I played them, they added a thick tone. They also felt better than the other brand I have currently been using, with better gripping action as well. This may be because of the string’s core design, which is unique. They get a thumbs up from me."
