Have an iPhone? Want to have a easy travel rig? Try the JamUp Pro for the iPhone 4s! I am using the iRiffport 30-pin interface for connecting my guitar.
Here are a few screen shots:
Guitar: Strat with Everything Axe pickup set (lil 59, JB jr., Duckbucker)
Fender clean (without and with chorus)
Fender clean with an envelope filter
