Equalizer

Pultec EQP-1A & EQP-1R type passive EQ circuit combined but with 8 extra low frequencies and 5 extra high frequencies.

PEQ500 is a full Pultec EQP-1A & EQP-1R type passive EQ circuit combined but with 8 extra low frequencies and 5 extra high frequencies. The Q (bandwidth) control for the high boost bell curve can go twice as wide as a normal Pultec and it can also do one thing I have never seen on any other Pultec or clone do. Pushing on the Q control will switch the high boost to a shelf with the Q control still varying the slope going into the shelf.
