Fuzz Version 2 - Now With Octave Up Version!
Posted: Sat Aug 01, 2020 12:31 pm
EDIT: Now comes in 2 flavors! Original, and Octave Up versions!
This is an updated fuzz distortion module. I've accomplished 2 goals:
1: Simplify the internal structure of the effect, so that it may be better understood and modified, and
2: Simplify the external controls, for more intuitive use. I also think it sounds better.
On the inside: The multictl's used to macro external controls are clearly labelled. The 3 distortions in the previous version have been swapped out for a single waveshaper, to simplify the structure and provide a more "Analog" sound. The DC signal for the PWM effect is now fully separated from the input chain, and simply added to it before the waveshaper. The PWM effect DC signal is based on the input signal's volume using a Sound2ctl, as opposed to being statically applied with a macro control. The input signal is no longer compressed before distortion, allowing for more nuance.
Controls:
BIAS: Controls the maximum bias applied for the PWM effect. Higher value = Thinner pulse at max volume. Zero Value = Unaffected, behaves as an overdrive.
GAIN: Pre-distortion volume control. Higher Value = More extreme distortion.
BASS IN: Bass boost pre-distortion. Will "color" the sound.
BASS OUT: Bass boost post-distortion
TONE: A simple lowpass filter. Range: 1kHz-14kHz
OCTAVE DRY/WET (Octave Up version only): Fades in an octave raised version of the signal, up to a 1:1 ratio. The method used for the octave up is simple, take the absolute value of the wave. This is how (most?) fuzz octave up guitar pedals work.
AutumnCheney on Discord graciously allowed me to post their demo, 'sawzer_fuzz_acid_demo.sunvox' as an example.
I have also posted an example of the first few bars of 'Spirit In The Sky' by Norman Greenbaum below.
