a lot of people use tools like sonic maximizer or the Harmonic Converger to get a better pod-sound. But I am looking for solution that cuts the fizz off a modeled sound and that enriches the tone with presence and bottom end. Perhaps you can try a tube preamp in the loop of the POD. When recording you give it a cut at about 10k and then add exciter or something. Never tried this - but perhaps it will work. What do you think?
