I'm considering a BA115T as my next amp. I've heard and played it and I'm pretty sure that it will suit my very limited gigging needs. The downside I'm concerned about is the "hiss" that's been reported. I played it a bit in a loud music store and couldn't detect any. But that was a loud music store. What I'm worried about is sitting in my quiet room at home practicing scales or such with a faceful of white noise. Which would be bad. Has this been a problem for any of you at relatively low volumes? Is it easily defeatable with the treble control? Am I likely to be going after the tweeter with wirecutters? Thanks!
