INDUCTOR EQUALIZER — Vintage Style 6 Band EQ Pedal
This recreation of the rare Shin-ei AF-17 equalizer is all discrete JFET and transistor design utilizing real inductors.

"The +/-6dB EQ bands are centered on 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, and 4kHz.
This EQ topology exerts a steeper curve on the higher frequency bands and a broader curve on the lower frequency bands."
I like that the lower freqs have a broader Q.
I also like that it uses "real inductors", 'cause I really hate EQs with imaginary inductors.
A great one to add to the Shin-Ei collection.

ran into this in another thread, and thought it deserved it's own. check out that funky bootstrapped FET/BJT sziklai input stage!
