IJ Research Stepped EQP Equalizer

Projects > IJ Research Stepped EQP Equalizer

Igor, evil genius behind too many projects to list, has returned from his laboratory Neve/Pultec Frankenstein of an equalizer. Igor’s unit is a passive equalizer in the vein of the classic Pultec EQP1, with a Neve BA283 output module instead of tubes to provide makeup gain. A couple of other new tweaks include stepped pots and an option to run a stereo unit in mid/side mode.

  1. trouble1macker202July 4, 2011 If the amp is only 450 watts does that mean it won’t be able to go near the about 1000W peak? Only asking becsaue I want to get a cabinet that can be used at venues, and I’m electronically retarded.
