This is an original unit from before it was acquired by Jim Dunlop. Based on the block logo and block stamping, it's likely from around 1980-82. The original model didn't have an LED lamp, so one has been added. It runs on a 9v battery. *Battery not included. There is some paint chipping on the surface, but it works fine without any scratchiness or other issues. A sticker is affixed to the top side of the unit. The unit itself is the only item included, as shown in the images. ~~~~~~ m133 Vintage vintage Booster
