Warm Audio EQP-WA Tube Equalizer - Vintage Sound

The Warm Audio EQP-WA is a modern recreation of the Pultec EQP-1A, arguably the most revered tube equalizer ever made. Rather than cutting corners to hit a price point, Warm Audio built this unit around CineMag USA-made input and output transformers — the same transformer brand found in gear costing several times more. The tube-driven signal path imparts the harmonic richness and gentle compression that made the original Pultec a mix-bus and tracking staple in top studios for decades. At its core, the EQP-WA offers two EQ bands with the distinctive Pultec boost/attenuate topology, including the famous technique of simultaneously boosting and cutting the low-frequency band to produce a tight, resonant bass curve that no standard parametric EQ can replicate.

In practice, the EQP-WA shines on sources that benefit from broad, musical tone shaping — kick drums, bass guitar, vocals, and full mixes. The bandwidth control lets you dial in the width of the EQ curve, while the high-frequency shelf adds air and presence without harshness. The transformer-balanced I/O ensures clean integration with professional studio signal chains, and the front-panel bypass switch makes A/B comparisons effortless. Housed in a 2U rackmount chassis, the EQP-WA brings vintage-class analog processing to project and professional studios at a price point that has made it one of Warm Audio's most popular offerings.
