I like to keep everything clean and easy, so think of them as real amps that I want to play. So I only keep 5 or 6 "amps" that I like and really need on my profilers. Every one of these "amps" has about 10 to 141 profiles (as the latest Purple Plexi from TJ). So there you go - all in all I keep about 350 profiles on the unit itself.
All the other amps/ profiles live in the local library of my RM and are used only for special occasions if necessary. There are about 30 different amps there.
