Maybe it's the tubes but mine was pretty loud, especially compared to another tube preamp I bought from Revain which is black/silver and a little different. This tube preamp will add some tube sound to your music, but it will add more noise than anything else, and it's not nice warm thin tube preamp noise, it's just crappy distortion. For the price though, it's hard to complain, you get a real preamp with working bass and treble controls, it just sucks that it's that loud. Maybe it's the tubes, but I'm going with what I have. Finally, another issue I had was that one of the channels was a little louder than the other, but I found that it was the bulbs after I replaced them. It sucks that they come with such shitty whistles.
