Effects rack suggestions?

[JeffMN]

Hey - I just picked up a Mark III combo. I'm thinking of how I might be able to automate the switching of the amp channels / EQ etc... with a rack effects system. Other than the G-System, what other rack systems offer switching like this, that can be stored in presets? Any recommendations?

Thanks!

GMajor, Replifex, Multiverb and I think the Xpression.

You can also get a Axess Electronics CFX4 to switch amp channels.
