Hello,

Few days ago I bought this amp as a second hand, barely used. Reviews said that it has a good clean tone. Anyway, I didn't expect much, it works well, nice sound but... There's some kind of noise, like resonating dirt, depending on a pitch of a note, and it only happens on lower register. It's not reverb related, it's not the speaker. With headphones there's no issue, and it seems that there's less of this noise when I plug in my phone to CD input..
Maybe the problem sounds familiar to you guys, perhaps with other SS amps, I have no idea what could it be (except that it's just built that way, part failure, poor part quality or loose connection...)
Would be gratefull for any feedback on this.
Thank you,
U
