Tascam footswitch help???

[Staredge]

I'm getting a Tascam guitar trainer from the 'bay, and I see that they have a momentary footswitch available for it.  I'm building an amp channel switch right now (yeah, I know it's simple but I don't do electronics...I'm a plumber), and would like to make one for this as well. Any ideas as to how it would be wired?  Don't have it yet, so I don't know if it is a ground switch like the one for my amp.
