I bought an Ultragain pro a couple months ago and I love it. I have an old tascam 12 channel 8 bus recording console that has decent mic pre's but I like the ultragain better. Aside from micing acoustic and doing vocals I like the sound of a bass ran through it.
Hey. Look into the Presonus Blue Tube. Its dual channel and goes for the same price. Theres a thread on it over in 'Microphones.' Im pondering purchasing one real quick here, and I've heard nothing but good things about it so far.
