How is the red one in the bridge? I'm currently looking at different options for my strat, leaning towards going HSS as I always find the bridge singlecoil too thin and weak compared to the neck and middle, and its too twangy/not compressed enough for rock imho.
That was exactly my dilemma. For choice, I'd have a humbucker in the bridge but the Red Lace Sensor is really hot, it's not as hot as a humbucker alone... but when I use it with my clean boost on my JCM900's dirty channel, it wails like a humbucker. Tone and sustain up the wazoo! Cleans up quite well, especially in position two which mixes with the Silver which is supposed to sound like a slightly fatter 70's singlecoil. The Blue at the neck is like a classic 50's singlecoil and they are a lot quieter than regular singles but do retain the thin glassy characteristics.
Dirty channel, lots of gain and just the Red is noticeably fatter than a singlecoil, hotter too... but for me you really need a clean boost or an EQ set with a mid-range hump to drive it into 'bucker territory.
They sound "true" enough to me to warrant having a Strat but still have enough power to melt your face. Singlecoils, real low power ones, are not for me but I still adore Strats.
Very worth it, it gave my Strat a whole new lease of life and prevented me from having to get it routed.
