Warm Audio EQP-WA Tube Program Equalizer

The Warm Audio EQP-WA recreates the vintage Pultec-style EQP-1A tube equalizer. Its 100% analog, fully discrete circuit keeps a full, harmonically rich tone while frequencies are boosted or cut, and can be used both during tracking and in mixing on vocals, drums, guitars, bass and full mixes.

The output amplifier passes the equalized signal through premium 12AX7 and 12AU7 tubes and USA-made CineMag transformers, restoring the insertion loss. Boost and cut can be used at the same time on the low band for the classic shaping effect, and five extra frequency points have been added compared with the original. The EQ section can be bypassed while the signal still runs through tubes and transformers for added warmth.
