The 470 resistor sets the Q and gain of the gyrator, so, in order to have a similar Q on each band uses the same resistor. The GGG eq uses the same negative loop resistor and the same pull up to bias resistor and only changes the caps...

1) can I eliminate certain frequencies (e.g. 4kHz to 16kHz); and
2) can I eliminate certain frequencies in between two frequencies? (e.g. 8kHz only)
thanks in advance.
