“Up until I started playing with the Fast Track Ultra I hadn't met a USB interface that I liked . . . The Fast Track Ultra has changed all of that for me.”
- Joe Randeen, HowAudio.com
"The Octane preamps give this interface an edge that puts it amongst more serious interfaces. Frequency response is good, noise level is very low and dynamic range is excellent. Harmonic distortion is minimal while stereo crosstalk is excellent. On playback, the guitar tone and the mics characteristics were faithfully recorded. The high impedance instrument input is also very good."
