Great for adjusting bass tones and pushing some low end information into the smaller playback system. I tested it before purchase going between full range monitors and mixcubes, and the difference was clearly audible. It's more versatile than you might think, with several different modes for different goals, uses, and source material. I prefer it to the competitors.
I am using this on my kick drum samples for electronic music. Adds weight and/or girth to anemic samples. A small amount of distoration goes along way! Before I was using the excellent El Fatso and this is a lot easier for the low end. A quick and easy way to pump up kicks.
Adds a great kick in the drums & make your bass fatter. Usually hung on 2 such plug on the channel.
