Our most popular plugin, the PTC-2A is a superb emulation of the legendary Pultec EQP-1A, one of the most sought-after vintage equalizers.
Separate LF Boost and Attenuate controls provide the signature Pultec sounds, while, as in the original hardware, a transformer-coupled tube amplifier stage further enhances the vintage qualities. Innovative filter technology provides a genuine analogue response without requiring conventional CPU-intensive techniques.
Available for Windows XP / 7 and Mac OS X Digital Audio Workstations.
