My growls are getting better yay!

The Curve is what creates The vowel sound that the growl has, the GE's are for making the "yoy" sound it has, the Stereo Detune gives it a softer tone, the Exciter is for saturation, and the Quantum multiband compressor has a preset on it that is an OTT replica, it helps bring out a more richer sound, the more you have, up to a certain point lol

Its an effect chain, they are all needed
