Yes, you can control your Orange Super Crush with the Stadium XL.
I have mine controlling my Engl Powerball 2.
Connect a TRS cable from your A/B Output Jack to the Footswitch In.
In Command Center, set up both Tip and Ring on the Lightning Bolts.
Since you have 2 channels, you need to find out what combination changes the channels on the Orange.
Channel one is probably 0+0 (Open + Open)
Channel two might be: 0+1 (Open + Closed), or 1+0 (Closed + Open), or 1+1 (Closed + Closed)
You'll have to test and see. But it will change channels on your Orange.
It's a good feeling the first time you stomp the footswitch and your amp changes the channel.
Also, you can do the same with C/D to control the Hi/Lo feature on the Super Crush.
Hope this helps.
