Up for sale is an unpowered Kemper Profiler Rack unit in great condition but does have some rack rash at edges . works perfectly but I never actually used it for recording since I bought it , it has just been sitting safely in my rack . All potentiometers turn smoothly, the main rotary chicken-head switch selects modes cleanly, and every individual input and output jack is solid and secure. The LCD screen backlight is uniform, bright, and completely free of any lines or dead pixels. [Optional line if applicable]: The unit comes pre-loaded with premium commercial profile packs from previous owner , saving you significant money on rig setups.*
