Hey! I just purchased an Ampeg BA-115T (USA made! yay!) as my replacement for my Orange. I really like the tone it has and seems sturdy enough, good features and price too. But I have a couple ?'s. 1) The tweeter hiss I have read about before, so I was prepared to hear it. Now, is there anything that actually comes out of the tweeter other than the annoying hiss? (a high note? lol) 2) I guess you have to dis-connect the tweeter to stop the hissing, right?
