CS is cleaner, more crispy sounding than C-Bomb. C-Bomb is aysmmetrically wound and has a lot of treble detail or 'hair', not as much maybe as the A-Bomb, but it's there. The CS is symmetrically wound and does not have that. There's definitely plenty of high end in the CS if that's what you want. I think the same is true of the RY.
the CS bridge is asymmetrical
I think it's pretty much an underwound c-bomb
had those 3 pups in my '73 lp custom and I agree with your tone impressions
the alnico bomb seemed a little more "wild" under gain than the other two, but still had slightly better cleans and versatility
the c-bomb was actually the most balanced sounding, despite of the higher output and compression
I never thought I would like it, but it's one of the best BKP's I've tried
I really like the cold sweat, but it's a more specific and unique sort of tone, while the nailbombs have a more generic sound, in my opinion
CS has more bass, but generally speaking CS (bridge) would be brighter than CBomb?
in those 2 YT clips I prefer CS way better.
yes, it is definitely brighter
similar amount of bass, but less body in the low and center mids
