Different guitar cables are due to pretty large differences in capacitance - in other words, it's no longer a valid cable.
It's an "audiophile" trick as old as they come, you add a resistor and/or capacitor in the "cable".
I wouldn't put such an "eq" beyond VSonic, but perhaps this is actually a driver change...
While it may affect some guitar cables, at the output and input impedance's of the gear in question, it's almost impossible to introduce enough passive capacitance or resistance with a cable that length to affect anything at it's mid high frequency peak. Any added resistance will be unmeasurable and we're talking picofarads when something like 1/4mf would be needed to have any effect on 10khz. Perhaps they found a cable reflection or the new cable just sounds less etched to mitigate the peak... or they did something else and are calling it the cable. I'm a believer that we can hear things we can't explain. Sometimes we try so hard to understand things that we get further off track.
I'm just glad it was addressed since I found it beyond my comfort level on an otherwise vg product.
