I bought an AC15C1 a few weeks ago and ever since the things been constantly mucking up. The Top boost channel has cut out once or twice early on, but hasn't done so since a few weeks ago. Then, more recently, it has started hissing whenever i play a note, and not regular distortion hiss, more of a white noise type thing. I have taken it back to the store twice where they have played it and the thing has worked fine, so i have taken it back hoping it would just stop, but it always seems to much up again. I recorded the sound it makes, so could you guys have a listen and tell me what you think?
Note that you may have to turn it up a bit, and also that the noise is not the microphone buzzing, its what i was describing.
