These cables will rolloff your upper frequency response DRASTICALLY, which is especially noticeable if you're using singlecoil guitars with a lot of presence and/or twang (Jazzmasters, Teles, Jaguars). I'm using a lot of high end cables (Vovox, Evidence Audio, Van Damme, Lava, Sommer Spirit XXL, Fishman Asterope etc.) and these are at the very bottom for me. The build is sturdy, the jacks are of high quality and cable wrapping is easy due to great flexibility. But the impact on my tone is simply too great. I've bumped them to footswitch duty (connecting footswitches to amps) for that very reason.
