This makes me terribly sad as I have SCNs in my tele and LOVE them. I understand why they didn't take off, but for someone who is regularly gigging, they are perfect. I personally can't stand single coil hiss, and never got along with it. These fixed that problem while keeping intact a great tele tone. I also wired up a no-load tone pot with them and completely recommend that.
Although guitar tone has always been a "Your Mileage May Vary" situation. For the indie rock kinda of tones I play these were perfect; for authentic bluesy tones, I probably would have chosen something else.
