My wife got me one of these for my birthday yesterday. I pluged it in and it noticed that there is a lot of noise generated by this amp by the tweeter at zero volume. There is a lot of hiss comming from this thing. I turned down the gain, highs, and messed around with the EQ settings to get it to go away. It's really annoying. I know tweeters can do this but I have never heard one this bad. I love the tone that these little combos produce and want to use it for jam sessions, practice and recording but I'm concerned about the noise. I never noticed the hiss on other BA115's that I have played but today I went to GC and played one and noticed the hiss this time. It doesn't seem as bad as mine but GC is a "mad house" right now so I couldn't tell how bad it was. Is this normal on these little ampegs? Or did I just get a bad one. I don't have this problem on my SWR Workingman 15 and even my cheap little Ibanez SW65 unless the volume is turned 1/2 way up.. Any insite would be appreciated.
