The Mighty Lite BT (BlueTooth) weighs next to nothing but can sound enormous. It gives you three gain stages - clean, overdrive and distortion - along with a great selection of modulation, delay and reverbs. It has auxiliary input and headphone output, can be battery powered, and has a corresponding App with which to control the Mighty Lite BT by BlueTooth. It's also very reasonably priced, in my opinion.
