Was back there today. I use an MBox 3. Although the preamps are OK, I wanted a dedicated mic preamp. Bought a PreSonus BlueTube DP V2. Tried it out with two singers. So far so good!
That looks like a lot of preamp for the money. How does it compare to the stock preamps in your interface?
It looks like it has been in poduction for a while, too. SOS gave it a nice review back in 2013.
My favourite budget mic preamp at the moment is the Black Lion Audio Auteur preamp.
I looked at several and it seemed like a very good deal. I'll need to use to more to be sure (and I can return it within 30 days if need be), but it definitely seems quieter. And there's a tube drive setting I've been playing around with. Will post back once I've experimented more.
That's the primary reason I bought it. Haven't tried it with bass yet, but with vocals they recommend a max of 30% and that seems to warm up the tone a bit. I'm still working on getting right combination of levels (interface and preamp). Trial and error for a couple of days I guess.
Yup. Ideally, you want to have the interface's input gain to be as low as possible so that you are using your preamp to do most (if not all) of the heavy lifting.
