Linking channels on 410-130

Steve brought up the subject of linking channels on another thread and I am intrigued but have a couple of questions:
1. Do I just plug into the #1 jack of one channel and run a cable from the #2 jack of that channel to the #1 of the other channel?
2. Will it matter which channel is linked to which by which I mean, what if I plug into channel 1 and bridge to channel 2 or vica versa?
I don't want to damage anything on my 410-130 so I appreciate some simple advice before I attempt this.

You are basically correct. No matter how you interconnect the input jacks, you won't do any damage to the amp (as long as all you plug in are signal cables, a guitar or an effect unit, of course).
1. First, plug your guitar into one of the jacks on one of the channels. (In this case it may not matter which jack you use, but to standardize I always use Input 1).
2. Plug one end of a signal cable into the unused input jack (Input 2) of the channel your guitar is already plugged into. Plug the other end of this cable into Input 1 of the other amp channel.
Now, you are driving the two channels simultaneously and you can get some cool tones by playing with the tone controls and level balance between the channels.
I suggest you get the guitar channel adjusted to create your basic tone, then connect the second channel and modify the controls on it to see what is possible. You could use an A-B switch to turn the channel link on and off, so you could preset two entirely different tones.
You can also add an effects pedal in this channel link, or even a volume control pedal which allows you to "blend" the effect in and out instead of switching it.
The possibilities are almost endless!
