I'am using a KMA Tyler Frequency Splitter where the low pass filter loop contains a slight overdrive, just to give it a little bit more grit but not destroys the bass and the high pass filter loop contains more overdrive/distortion. While this setup works for me, it takes an enormous amount of pedal space. I have to populate two loops with stuff. and the Tyler is not a small pedal either. The aftershock could maybe replace a lot of that stuff. I just don't know, if I could setup both chanels in paralell and put a low pass filter before one overdrive/distortion of the that channel and a high pass filter on the other channel before the second overdrive/distortion. Code: +--- Low Pass Filter --- Overdrive/Distortion ----+ | | Input --+ +-- Output | | +--- High Pass Filter --- Overdrive/Distortion ---+ I need the placement of the filters before the distortion/overdrive effect! The low or high passed input signal changes the operation of the distortion unit drastically compared to a dry signal and putting a low or high pass filter after that distortion unit. I took a peak into the manual and at some reviews but all I found, was a parallel mode with the EQ sections after the distortion units.
