Interesting business model. So, are you not going to manufacture anything from the crowdfunding campaign? What are the backers going to be getting as a product - the software, 3D print files, circuit board designs, build instructions, and tutorials?

Thanks for the encouragement on RiffPod. Yeah I have looked at iRig - RiffPod has 2-channel (mic + guitar) streaming, has an headphone/amp output and supports iOS and Android. Those are the main features that set it apart from iRig.
