First off, great customer service! I received my Jammy, and there was a small product fix needed. The Jammy team was super responsive, and gave me great how-tos to fix it, without the need to send mine back in. As for the product, they are constantly making improvements to the app and firmware. I use my Jammy in a mobile rig, helping me to learn guitar on the go, and it is an ideal backpack companion. It's a solid product, and look forward to the next releases.
