Hello there,

Just need some help with this Eq/fuzz I am working on. Its based on 5 bands of the api 560. I have this circuit working on half rail at the moment, and the response seems to be fine in the sim.
I've managed to pull the middle three bands up to 4.5V using the 910k (R31, 27, 4) resistors, in parallel with the 910(R29,25,8) to ground. My question is, why does it work like that? Is it only because its in the sim that it is responding that way? I assumed placing the cap(C17,15,8) in the middle would parallel them, but I don't get the 4.5 raise when the cap is placed there.
