Noble/Nobelium/Neptunium uses a modified Fender tone stack, which does not have fixed frequencies for any of the controls; the frequencies affected are interactive between the three controls.@Mr. Sushi- With the Neptunium, is there a way to tell the approximate amount of mid cut and the approximate frequency cut when the settings are-
Low cut On
Bass at 3 o’clock
Treble at 1 o’clock
But with the controls in that position you're probably looking at something like this.
The HPF will roll off 6dB per octave below 90Hz, which I unfortunately don't have a way to plot, but this gives you an idea.
