It does give me more gain, but that's not why I used it. The tubes in the ultragain were replaced with svetlana tubes, and honestly, it made a difference. I had all my other pre's at another location and I really wanted to record the acoustic, I was just antsy yeah know? You get excited about a song and you've gotta record it right then. So I used the b-ultragain. The only reason why is to add a lil tube warmth to it. It doesn't add a lot, it hardly uses the tubes, but it made the difference that I needed.
