I opened the package, sceptical. i've tried tons of strings through the last ten years, but i had a hard time really hearing the difference. Every now and then, i found something that felt a little different, or lasted longer but nothing that really made me stick to one brand.
And these did not look any different than any other strings.
I took the first cable cutter in sight, a little too small now that i think of it. I had used it before though, but when i was cutting the low E string, the cable cutter broke in two pieces. I have never, ever, broken a cable cutter before on any guitar strings. To me that is an attest of how strong these really are. I've put them on all of my guitars, and i have a hard time describing, what these strings have done for me in a way that justifies what i feel. My Parker, that has well rounded middle output pickups, suddenly has an even sparklier clean tone, more grunt when chugging, it stays in tune for 3 songs, instead of 1-2 whenever i'm playing live. I've found the strings i've wanted and i'm not going back.
