I purchased this talk box and was sent the wrong power supply. I also didn't receive the special clip that holds the talk box tube on the stand as promised. If this was just the regular Boss style wal-wart it would be no problem. But it a specialty 18 volt supply tip negative and doesn't work with common power supplys. Though he sent another power supply, it too was incorrect. I sent him the link for the correct supply but he ceased all communication with me. I even sent him a Paypal invoice. No communication at all means negative feedback.
Now I have a talk box that I can use until I spend Another $30 or more on the proper supply. I also need to buy the tube clip and who knows how much that is.
If you promise items to be included with an item you're selling you should know that you have these in you possession before promising anything.
