Yep. In the case of removing fizz it's easy. For instance, with a spectrum analyzer you can clearly see activity in the 9.3KHz range in the OP's sample, so I'd do the same thing in the KPA that I did using Samplitude. I'd use a Studio EQ in one of the post cab effects slots and set the Mid Frequency to 9372KHz with a slightly narrow Q and cut it by approximately 6dB.
In Samplitude, I actually made a 6.9dB cut @ 9.3k.
Anyway, you can do the same thing in the KPA if you know what frequency you're looking for(I use a spectrum analyzer). EQ matching is obviously another story.
I use EQ to cut fizz because I've found that cutting presence or treble is akin to using a machete to remove a splinter.
I tried this last night on my beloved MBritt 70 SL3 which sometimes had that high end fizz especially when using the neck pickup.. it really cleans up the sound. thanks for the tip!
