Circa 1980s Eventide H3000S Ultra-Harmonizer.

A revolutionary 1980s digital audio processor known for its versatile multi-effects, including pitch-shifting, reverb, delays, and modulation. 

It was celebrated as a professional studio standard for creating both subtle enhancements and radical sound transformations, becoming particularly popular for its impact on guitar tones and vocals. 

Its legendary status stems from its unique algorithms, including a famous micro pitch shift that created a distinct sonic quality, and its role in shaping the sound of numerous hit records. 

Great on everything from guitar and vocals and more.
