I have something similar. Samson Power Brite for power, Axe FX and a Matrix. The Samson is basically a glorified power strip. But its nice to be able to switch everything on or off with a single knob. Plus it has lights. Samson sits at the top, Matrix (as it is the heaviest), at the bottom, the Axe FX in between, together with a front rack panel with all my connections, because I hate having to fumble in the darkness of a stage in the back of a rack case.
The way I've routed it is:
- guitar input in the front input of the Axe
- unbalanced outputs L & R to the Matrix,
- balanced outputs L & R to a pair of XLR connectors on the front rack connector panel if I want to go straight into the FOH mixer.
- Matrix outputs L & R to a pair of jack connectors on the front rack connector panel if I want to use some cabs.
There's some other stuff in there too. 2 Korg Kaoss pads into a 6 in 2 out rack mixer, provisions to insert a keyboard via the front rack connector panel into that rack mixer as well, and 2 additional XLR outputs on the front rack connector panel for that mixer to send my Kaoss pads and keyboard signal into a FOH mixer as well. But that's basically a completely separate non-guitar related setup.
