Hey. As i look through my most recent catalogue of equipment in this magazine i can't help but notice the various types of hardware such as equilizers, crossovers,filters, effects, reverbs, and enhancers. What the hell? Is this hardware necessary? I'm sure it is but how much better will the sound quality be coming from these units then using plug-in software that's much cheeper and seemingly easier to use? Who buys these things? Just talk to me like i'm 4, please explain. Thanx.
