You are looking at a Kemper Profiling Head (non-powered). It has the latest OS and sounds fantastic. It is in excellent condition. The display and lights are perfect and the knobs feel great. The effects are great and it is easy to edit onboard or with the free editor from Kemper. I'm only selling it because it is more than what I need right now. I'm not currently recording guitars very often on projects (maybe one small track here or there) and so it mostly just sits next to me unused.
