I purchased the pacifica a few weeks ago after renting if for a month earlier in the year from studio Economik. It has a very fat sound, but still very clear. I was originally interested in it for recording acoustic guitar, but it is excellent on heavy distorted guitars as well. Read more
Do to it being so clear, you can multitrack heavy guitar (7 and 8 string as well) without to much worry of things getting muddy. It may not have as much "character" as some other preamps, but the pay off is a very clean mix. My only real critic, is the DI's. They sound fantastic, but it would be nice to have thru jacks as well to go to a live amp. As someone how reamps a lot, the DI is perfect, but not having a thru jack means that you will have to use some sort of amp sim to monitor the track, which I don't find very inspiring. Hardly a deal breaker though! Excellent unit!
