Up for sale here is an incredibly rare variant of the Sears 257 Drum Machine. It was made by FGE Enterprises in Addison, IL. There's not very much information on it anywhere. I assume it was the original model and Sears bought out their patent and sold it as the 257 model. This is the only model I have ever seen. The only other King Beat I've seen is the King Beat 7. This is a once in a lifetime chance to get the ONLY King Beat Rhythm thats known to exist. 

It works great all the beats play through no probelm. It's in great cosmetic condition, but the pads it sits on are all broken except one. Returns are not accepted, you are buying only the device itself. International buyers contact me. What you see is what you get.Thank you for your time, and happy bidding!
