Marshall/ Schecter strings

The weekend has kicked in, it's a rather fast-moving November when there are things to do & places to go. Was at Davis yesterday, bought the Marshall strings you see above- so now you know, Marshall have strings under their name. The Schecter you see here is complementary from Janet, it's an 8-string set: 10 - 74. The gauge per se is rather overwhelming but i'll try them in my Ibanez RG8 which is current strung with a set of 9 - 65...

Q: What do the brand names above have in common?

A: The strings are manufactured by another brand name. D'Addario makes the Schecter set while Ernie Ball handles the Marshall set.
