It creates high-frequency harmonics. Makes vocals, guitars, cymbals sound brighter and more "airy" without being harsh.
2. *Adds punch and definition to bass*
The "Bass" section adds low-end harmonics. Makes kick drums and bass guitar feel tighter and punch through the mix.
3. *Adds stereo width*
The "Process" section widens the stereo image so your music sounds bigger.
4. *Makes dull recordings come alive*
This is why it was popular in the 90s. If a mix sounded flat or muddy, the Exciter 3000 would bring it back to life.
