I have Version 1 of POD Farm which came with the POD Studio UX2
Most amp models have knobs for drive, bass, middle, treble, presence and volume that can be tweaked allowing for hundreds if not thousands of possible tones.
To get familiar with the amp models, I decided to record clips to be able to compare each sound. Picking an amp model in POD Farm automatically pairs it with a pre-set cabinet, room position and one of three microphone types, all of which can also be tweaked so I’m not exaggerating when I mentioned the number of possible tones that can be had with this piece of software.
