I want to tune everything to 420Hz. 
It would be a slight increasing / decreasing dc offset, maybe moon is better then.
I recently made a bell synth based on the golden ratio. Just some sines and some ringmods, tuned by a ratio derived from the golden ratio. It can sound a bit like a gong, a steel drum or church bell kind of thing. Other ratios in tuning would fail to produce the same effect. Another property of the golden ratio when applied to oscillations seems to be interesting entropy going on, for example with low frequency osc’s beatings.
Here my bell synth based on the golden ratio can be found:

Youtuber and Bassist, Adam Neely cleared up the 432Hz topic. His videos are entertaining as well.
“I can make a wicked, Noise like a cricket, Rubbin’ his legs, my rhymes are like eggs”
Plot twist: 432hz is actually The Brown Note
The brown note is a myth according to Myth-busters.
probably not enough amplitude
