Every distortion is empty, but moreso, because u have an overabundance of dirty and not nearly enough low end, and this CANNOT be fixed with an equilizer.
Instead of getting a different unit, or anything drastic, I did some research and decided on getting a tube preamp to add that warmth and boost in volume. I tried the Presonus TubePre for one channel, and i loved it so much, i got its big brother, the Bluetube DP. Now the PodXT runs in stereo, like it should live/recording, and the acoustic sounds are even more believable, where before they sounded fake to a degree.
Of course nothing sounds exactly like the original, but the Pod has definately opened up my eyes to what eventually i will end up using full-time, without having to search for it and buy things continually.
In my opinion, the Pod is a great unit, but one meant for finding your sound rather than using it for your sound...its also awesome for recording =)
