My usual we-agree-to-disagree here ;)
I'm not into metal, I don't listen to 90s metal, I don't play metal, and I quite like the RR bridge on my SG, even for bluesy stuff. Yes, it's a rather modern sounding pup, and yes it's quite tight and aggressive (well, the bridge at least, don't have the matching neck). Not my first choice for pristine clean tones, but I like it a lot for about-to-breakup to full out hi-gain tones. Now there might be better options for modern mid-gain LP tones, I didn't try the whole BKP range ;)
