Man, what great strings for metal.I played with super thick 62s for drop A. Talk about a test of product.I got 13s for my bottom string. Bends as easy under that tuning as any 9 standard.These strings will not break. I doubt ever. I doubt under any load other than my full strength using both hands. Its not an exaggeration. I tuned up to B. Wrote a few songs. Strings sound on point. Never had to change em out to go up a step. Tuned up to C. Just to see what its like. Nothing wrong, tension was good tone was great (since that is what they were actually designed for is drop c not A)Thats kinda my point. They dont make a pack that says DROP B or DROP A on it. But they do got DROP C.I had to build my own custom set by choosing different packs to finally reach 62/46/36/26/17/13My metal riffs have great low end and chug propertys , my mid range is even and the highs wont pierce your ear but give you a high twang instead. Great balance and I thrash and I scratch em with the pick and I pull hard on them before tuning to max out the slack, I counter tune the open strings with the fretted strings for a great overall balance. (You want open strings barely flat so that fretting strings are slightly sharp or in tune.) The strings hold up to all of this. On Drop A. Drop B or Drop C. I freaking love these strings. My pickups are EMG 81/85 and the guitar is an ESP 22 fret.YES I said 22 fret small ESP running DROP A. It should not be possible but yo....D'ADDDDDDDS
