So I was reading the schematic for the Traynor TS-50B to try find out what the tone controls do. I have kinda always been confused looking at them but today I realized the bass and treble were quite simple to run by themselves in the tone stack calculator with a Marshall stack if you get creative and well:
That's a Traynor if I've ever heard one! The trouble is the mids, however...
I just cant wrap my head around it. My first thought was either some notch filter or BMP-tone but a quick check on AMZ confirmed it is not. I looked at some schematics of RC-bandpass filters and I kinda can see the semblance but I am not really sure. What i do understand is that the pot "switches order" of the high and low-pass sections but I have no idea how this would graph. That is if I'm even right at all, I have extremely limited knowledge of electronics but I would like to learn a bit more. Any ideas? i would love if someone who knows about this kinda thing could help out. These traynors sound awesome and it would be super cool to know a bit more about why they do.
