Electric guitar is NOT about freedom...
...well maybe it is, but it's also supposed to be about sound and tone!
I have a POD Pro - it is a useful tool... but I have yet to get a convincing clean sound out of it. However, it does give you a palette of tones to quickly choose from, especially dirty ones...
But don't forget, it is a "modeller" -- it's a device that mimics the "REAL" sound of a mic'd cab. So the truth is, the real thing (a mic'd amp) will ALWAYS be better than a "simulation".
Where that concept goes wrong is if you don't mic the amp properly, or you use an incorrect mic, or bad placement, or a bad room.... then yes, you're probably going to get a better sound out of the POD (since you can buck the whole concept of recording technique, that way - plug the POD direct, and off you go!) But then you're confusing the ease-of-use and relative simplicity of getting a guitar sound via the POD, versus the real sound of guitar/amp captured thru good and proper recording practices!
You want a practical example of a sound that will be better than a POD? My American Deluxe Strat or Guild semi thru my Yamaha
DG100-212 combo (clean!) mic'd with
a Shure Beta 57......
I guarantee you won't get THAT sound on the POD!! (I know, 'cos I've tried... hard!!!) The POD just comes out mushy by comparison.
AS I said, the POD is another option to add to your creative palette.... but it can't "replace" the real deal! There is always "the best tool for the job..." and real, by definition, must *always* be better than simulated, no matter how effective "simulated" can be!
