It wont make a bad mix sound great. I had the makie 1604, I tended to use it for subtle distortion on my bottom end and it worked quite well. Ive yet to find a digital plugin that gets that warm analog distortion quite right on the bottom end. Plus I didnt need a radiator in my room when that thing was running, kept me right warm in winter.

What is your current setup like? The is not much point unless you have a decent sound card and monitors.
