The pig 90 bridge to my ears is just darker than the stockholms, especially when playing clean. It does not have that "chime" as much. But honestly, I couldn't tell much of a difference when playing in high gain settings. The difference was maybe in response. I felt the stockholms were more responsive, maybe have slightly better pick attack, and like I said, less saturated. I just found no reason to use the pig90 after trying both the pigs and stockholms. The stockholm does what the Pig90s can do without being super high output and saturated. I would also say for certain that the Pig90s are more limiting in terms of sound. Stockholms are definitely more versatile. The pairing with a supermassive neck is the way to go too. The pickup set (stockholm bridge and supermassive neck) turned my SG into a totally different animal, really did. But I was going from mini humbuckers to these BKPs...Again, I'm not a seasoned professional musician with superman hearing powers. But this all is just my gut feel. Hope this helps!
