Excellent top end brightener. Really opens the sound up, slightly reduces the low end, and is really useful when buss mixing.

This modern-day exciter and tone enhancer is great for pulling up sections of frequencies and emphasizing the harmonics in a way that sounds REALLY good. The lack of analyzer or numbers in terms of frequencies forces you to dial it in purely by ear until it sounds just right. It's great for giving richness to audio that lets it cut through the mix without any phasing or clashing.
