The Rack Pack consists of 58 Studio Profiles of a couple of classic 80's rack preamps, the ADA MP1 and the Mars JMP-1. These tube-based preamps bridged the gap between classic tube amps and early digital processors. Many classic recordings were done with these units and some artists still use these on tour.
The JMP-1 has a classic midrange growl, living up to its gold metal faceplate. The ADA has a creamier saturation and much more gain on tap. A buddy turned me on to a .pdf file that has suggested settings for a wide variety of tones using the MP1, so I made good use of those settings in these profiles. Many of the profiles are named using the initials of the guitarist the suggested settings was trying to mimic. I think some of them got pretty close. I also did a few of my own favorite settings as well.
The Rack Pack was creating using the latest 4.x firmware. Please forgive the playing in the audio samples as many of these weren't exactly in my wheelhouse. Thanks!
