Pultec Style Tube Equalizer The EQP-WA is a re-creation of the most renowned tube Equalizer in studio history, the Pultec EQP-1A. Not only does the look and feel of the EQP-WA match the classic Pultec units, but the sonic quality has been carefully considered by using top-end components such as CineMag transformers and premium tubes. This fully discrete Tube EQ can pull euphoric sonics from any track and bring a brilliance and luster to mixes that's nearly impossible to achieve inside-the-box. We are proud to have once again redefined the industry standard by bringing a fully professional-grade equalizer to the market at a price that's just as remarkable as the unit. Premium Components The EQP-WA is a high-voltage tube equalizer, utilzing CineMag USA Transformers and two premium vacuum tubes by Tung-Sol. A Two Tube Operation The EQP-WA operates on two tubes: one 12AX7 and one 12AU7. We proudly use Tung-Sol brand tubes in this product for their sonic richness and open sound. These two tubes are socketed for easy swapping and replacement.
