4-Band Equalizer

4-Band Equalizer
Utility EQ pedal to shape the sound of your favorite effects.
This is a 4-Band Equalizer, suitable for pedalboards or for direct use with instruments (guitar, bass, or other instruments with pick-ups), or even with synths and other line level devices.

Its 6 simple controls include:
▹  LOW pot, to boost or cut a low frequency shelf down to 15Hz.
▹  LOW MID pot, to boost or cut a ~420Hz bell.
▹  HIGH MID pot, to boost or cut a ~ 3.5kHz bell.
▹  HIGH pot, to boost or cut a high frequency shelf up to 25kHz
▹  VOL. pot, to control the output level. At max position, with all EQ pots at 12:00 position you get is unity gain.
▹  Foot-switch, to completely bypass the circuit (true-bypass)

Setting all EQ pots at middle position (12:00) you get flat response.

▹  Input impedance: 1MΩ
▹  Output impedance: 100Ω
▹  Power supply: 9-24V (using voltage higher than 9V gives you more headroom)
▹  Current draw: 8mA
▹  Enclosure Dimensions: inches: (4.45 x 2.4 x 1.25)  ||  milimeters: (114 x 61 x 32)
