Besides an equalizer, it has what a bassist needs in the first place.The limiter is very versatile and user friendly, and after a while you'll think you cannot play without it.The enhancer effect is awesome! Not any kind of distortion or so, it only makes your bass sound excellent, something you can use all the time, and not for this or for that song.It isn't perfect though, it makes a lot of noise when you're not playing, specially if the enhancer knob is turned near full clockwise.It works great as a power booster, too.
