Based on the pot date, this is an MXR Dyna Comp from the script logo era, featuring the 77-year model's can-type CA3080. Since I bought it used, there's a hole for an LED, and a DC jack has been added. It cannot be used with batteries, but it can be powered by a power supply, making it easy to integrate into a pedalboard. The switch has likely been replaced, and one screw is missing from the back cover. Please check the images for other parts details. Body only. I have confirmed the operation for the listing, and it is currently working without any scratchy noise. As it has been used for a certain period of time, there are cosmetic damages such as discoloration and paint peeling on the enclosure. Please feel free to comment if you have any questions or would like to negotiate the price. Type: Electric Guitar Manufacturer: MXR Type: Electric Guitar Manufacturer: MXR
