From Reverb:
You won't realize you need the TC Helicon Mic Mechanic until you try it. It adds just enough subtle reverb, warmth and correction to make your vocals sound like a better version of yourself. Great for simple home recording (without messing with all the settings in your DAW), but it's especially strong as a live performance aid. Correct for overly harsh PA systems or a rough night with a few simple turns of a knob.
The TC Helicon Mic Mechanic is a stage-ready vocal processor that includes several reverb and delay settings, as well as pitch correction and tone enhancement.
