guitar tone question

[Harry Hughes]

Keep in mind that most guitar speakers are only rated up to around 5kHz (though there will be content up higher). Throw a low pass filter with a gentle slope on the track and pull it down till the high end junk is gone.

Fixed
The rating is more about where the speaker starts to significantly drop off. There will ALWAYS be content above what the speaker manufacturer's claimed highest frequency production quoted in the specs.
But then again the OP is working with POD Farm, not real amps anyway.
