Cool...
Ill just show you with a lot of stuff that edge has or that you can replicate...
Here is the memory man, it's worth about 195 euros but you can play mostly all of their early stuff...

The Whammy is another cool effect to use but it is over 100 euros..Edge uses this on Hold me, thrill me, kiss me, kill me, Even better than the real thing, a part of Beautiful Day, Mofo (for the screaching sound) and Gone.

Now for Zoo Station, Mysterious Ways and The Fly, etc. You can buy the Korg A3...The Korg A3 is out of production and is found on Ebay...You will sometimes find them for really cheap or really expensive like this one..

If you end up buying it, make sure it is with the SP-1 card because that is where Edge gets his sounds...
Now this one is very over the top in prices BUT you will get 98% of Edge out of this...Some people argue with me about this but I've also talken to people and have used their system and I find THIS system to be the best out there to copy Edge's stuff..

You even have a harmonizer in there (which is a big part of With Or Without You)
To play with or without you you need a harmonizer, a volume pedal and something called an E-bow...
E-bow is something when you turn it on, you have to press it against the guitar strings then vibrations come from the guitar to the amp...

The volume pedal is when you're playing the E-bow and the Harmonizer and you can make that very cool noise taking the volume pedal up and down..

As you can see there is so much to his rig...I can go on and on...
Is there something else in his rig you would like to replicate?
What amp do you have?
