I'm ready to buy one of the new Fly Rigs. I really like the idea of having a lightweight plug'n'play rig available if my tube amp dies suddenly. They can also all be plugged directly into a mixer or a PA. I'm not sure which of the three in the review to get. I like the sound of the Paul Landers model except it doesn't have an FX loop. So I'm leaning towards the Fly Rig 5 V.2. Has anyone been using any one of these three?
