Re: Boss Metal Zone Mods?
Simulation shows a 6db peak in 100 Hz and a 10db peak in 5 kHz.  
 
My *GUESS* is that each Sallen-Key biquad is simulating a series RLC circuit. At the resonance frequency these RLC simulations show smaller impedances and then the gain of the opamp stage is higher. Outside the resonance frequencies they look like open circuits and the opamp behaves like a buffer.
