3-band passive EQ

Decker is a simple FMV EQ circuit similar to the tone stack found in many classic amps.  A volume trim control is also available on the front panel to compensate for any loss or boost in volume caused by equalization.  The op amp stages of this circuit can easily be tuned to provide a healthy amount of boost and/or overdrive if so desired.  It can be built as a stand-alone pedal or as an add-on to a gain circuit in need of amp-like EQ.  By adjusting values, a wide range of tonal options are available.

Sale is for PCB only.  You must source the components and build the pedal yourself.  To make foot switch wiring easier, we also suggest you buy the 3pdt utility switch.  

Build documentation can be found here below.  Please read before purchasing.
