I just received a used EBS Microbass II that I bought off of ebay which was listed as "New - other" "never actually used". I received it this Thursday and tried it out that night. It work great. Everything on it worked as it should. I put it away and didn't use it until today (two days later). Now, everything is distorted. I hook it up to a 1-spot adapter and I get lights but no signal. I install a new 9v battery, no signal. I hook it up to an 18v adapter and I get a signal but everything is completely distorted. All of the features work but again, everything has a layer of distortion on it. I get the same thing no matter which bass I use, and I made sure it wasn't my headphones or my cable. Any ideas as to what it could be?? I'm very disappointed because I absolutely love these EBS Microbass DIs.
