Unlock the legendary “Pultec Magic” with modern precision and vintage warmth.

Inspired by the iconic 1970s Pultec EQP-1R, the Horizon Discrete Program Equalizer delivers silky highs and thick, rich lows with authentic analog character—reimagined for today’s pro audio workflows. Built with discrete components and a custom “flying” gyrator circuit replacing traditional inductors, this EQ offers crystal-clear high-frequency boosts with zero hum and ultra-low self-noise.

Whether you’re performing live, mixing creatively, or mastering with transparency, Horizon adds musical tone and warmth that breathes life into every track.
