I'm using my gibson les paul, and my gt-8 plugged straight into my pc, i do have a podxt pro but still setting that up for the songs so not used it much yet.
The set up for my boss gt-8 is:
OD-1 with drive set to 40 and no direct sound so its all overdrive
Single Delay: 420ms, Feedback 30
Reverb: Room but only about a thrid on
Phaser: Bi-Phase, Rate at 20, and thats about 70%
And the Wah for the solo which is used on and off through out.

Chain: Phaser, Wah, OD, Delay, reverb

Will be posting some more videos soon (next day or 2) might do a couple of U2 ones
