Hi folks
I'm trying to study Steve Dove Eq
simulation and proto is fine except Q pot, at the moment i can use recycled-old 5steps dual rotary sw
so the resistor progression i used change Q in a good manner(shape) but gain goes down directly proportional...
reading different posts and articles i maybe understand i should use a Log and AntiLog response for this dual gang pot
at the end on simulation i spent little time changing values till a found a good balance.... Q shape changes and gains for all bands are quite matched now

am i close to the result?
thanx for your attention and support

Measured Bw from 5 to 0.65 with that resistor values... Compared it with old digidesign eq...
