[sdiy] hi shelving filter

[mark s]

greets list

i am building a mic pre based around the SSM2019.  i would like to add a 
high shelf filter with cut or boost starting at 3 selectable frequencies. 
4k, 8, and 16k.

obviously this is for vocals so it's gotta be pristine-clean and the 
phase/time-alignment must be good, or it's just not worth implementing.

1. bandpass filter from 4k/8k/16k to say 100k ?
2. active HPF with make-up gain (i'm not sure how to do this)  ?

does anyone have experience with inductors?  what are they like in real life ?

cheers
