HGE Contraptions Core Shaper Parametric EQ Handmade Clone

HGE Contraptions Core Shaper Parametric EQ Handmade Clone (167th pedal built)

This is a nice versatile pedal with quite useful tone shaping!

Has a parametric mid frequency eq (Mid knob + Mid Frequency knob), which also has Bass and Tone controls. Can also be used as a booster of sorts, in conjunction with the Volume knob. Please note that it will have those OP1678 HiFi ICs seen in the third picture, these reduce overall hiss by 3dB!!(tested vs the stock ICs 5532 and 072 in the other pics).

In detail, the gain is +-16dB, the frequency sweep is about 300 to 3.3K, the Q is 2.4 in HI and 1 in LO. The beauty of this circuit is that the Q stays constant across the whole sweep and so does the gain.

Before this, there's a low gain input stage which gives a strong input signal and buffers the input while avoiding clipping at guitar levels throughout the circuit. The charge pump helps with the headroom, providing a +-9V supply so the boost levels can be reached without problems.

Following the bandpass, there's a very standard Baxandall 2 band EQ to take care of low and high frequency and add quite a lot of flexibility to the circuit when combined with the bandpass.
