I agree... M-Audio MidiSport 2x2 Anniversary Edition (and two midi cables). To access Axe-Change, log into Axe Edit and click on "preset manager". On the upper left half of the preset manager screen you will see Axe-Change tab. Click it, enter a user ID and a Password - I used the same ID and password as this site, however, you can use any ID and password. Thats pretty much it! Also, if you are interested in making recordings on your Mac, you can buy an 1/8" TRS male to dual 1/4" TS male "Y" cable (you can find one at Guitar Center or just about anywhere else. $8 - $25). You simply plug the two 1/4" plugs into Output 2 (left & right) on your Axe, and the 1/8" end plugs into the audio input (next to the headphones jack) on your Mac. With just this cable, you will be able to record your Axe (in stereo!!) directly to GarageBand. Good luck with everything!
