This Manley Enhanced Pultec Mid-Freq. EQ is particularly suitable for instruments with a focus in the mid-range, such as guitars, vocals, harmonicas and violins, etc. It has the same functions and specifications as the Manley ‘EQP-1A’ version. The differences lie in the passive EQ section: on the MID EQ, the DIP and PEAK controls apply steeper bell filters to the selected frequencies, allowing for more precise control over the essential mid-range. This makes it an ideal complement to the EQP-1A Pultec EQ.
