Hi all. Looking for some help before returning my new Beat Buddy. I have a constant hissing, like a shhhhhhhhh sound in the background of my brand new Beat Buddy. Really annoying. I tried everything I could to eliminate it (well, almost everything). I noted that with the volume all the way down, there is a constant shushing or noisy hissing. With the card in, the beat plays lightly over it. Take the card out, the beat stops, but the hissing continues. To me, this may indicate that the problem is internal to the BB, not interference from the outside. I used a $60 cable to hook up to the amp. No guitar (or anything else) in the input. Problem persists with the foot switch disconnected.
Has this been a common problem? Is this something a firmware update will resolve? I’m worried that even without the SD card the noise remains the problem has nothing to do with the card itself. Any advice will be highly appreciated. Thanks.
