If ever there is an official “Audio Technology Hall of Fame”, it will definitely include a shrine to the legendary Pultec EQP-1A. We pay homage to this audio-processing pioneer that has graced so many recordings, with our EQP-KT Classic Tube Equaliser. And while vintage Pultec units are extremely rare and expensive, the EQP-KT is amazingly affordable – and designed for the 21st Century. Mastering quality equalisation, at a price point that makes the EQP-KT equally at home in your studio – and your live rack!
