The Cartec EQP-1A is a hand wired valve equaliser, designed to recreate the distinctive sound and features of the classic 'Pultec EQP-1A'.

The Cartec EQP-1A is designed to meticulously reproduce the original 'Pultec' EQP-1A. Thorough attention to detail has made this product a favourite with engineers who have become accustomed to the sound of the original units. The inherent flaws associated with the original power supply design have been maintained, as they impart a unique character which is lost with modern 'improvements'.

Each unit is assembled with selected high quality, low tolerance components.

  • ECC83S, ECC82, and 6x4 valves, 20, 30, 60, and 100hz low frequency boost and attenuation.
  • 3, 4, 5, 8, 10, 12, 16, 20, and 30khz high frequency boost with variable bandwidth.
