To be a guitar-wielding rock star, you need a lot of gear. Your axe will only get you so far. Without an amplifier, not many people are going to hear you shred through a wicked solo. Not all amps create the same sound -- you'll have to pick one that gives you the effect you want. And effects pedals open up your options even more. All that gear takes up space and can be a pain to carry around.
"But that's what roadies are for," I hear you say. I agree. But when rock stars are just starting out, roadies can be few and far between. The sad fact is you'll likely have to schlep your own gear from gig to gig. And it can be awfully hard to rock out when you're on the verge of developing a hernia.
But what if you could consolidate all that gear into a single mobile device? What if this device could simulate the effects of all those pedals and amplifiers? And what if you could switch out virtual gear on the fly, giving you nearly limitless options?
As it turns out, there are products on the market right now that will let you feed your guitar output through an iPhone and use it as an amplifier with all the bells, whistles and wah-wah pedals. How can that be possible?
