[sdiy] 45 vs. 90 degree pcb traces

[Jimmy Moore]

This came up on the AH "behringer RD-6" thread:

>>Until the PCB traces are curvy (like on a 2600 or SEM) it's never going
to sound authentic.   Electrons don't like corners.

I had picked up similar folk knowledge from my first engineering job
working alongside techs, EE's, and designers.  I went looking for a more
technical explanation on why this is the case, and it turns out it is NOT:

(Notable exceptions being RF, high speed, or high voltage layouts)

This and another
<https://electronics.stackexchange.com/questions/226582/pcb-90-degree-angles>
resource
debunk the pcb corner myth on EMI effects.

Is there any other tangible (audible) impact this decision could have for
music electronics?  I think not, but I'd love to hear from other more
experienced engineers on this (hopefully not tiresome) topic.
