I think the POD vs. real amp is somewhat of a parallel to the Analog vs. Digital recording debate in a weird way.
Yeah, a real JCM800 professionally recorded sounds better than the POD model, but does it sound that much better that the POD is unacceptable? For some yes, for some no.
Does a 2" Studer sound better than Pro Tools? Many seem to think so, and digital recording was scoffed at initially (and still is), yet Pro Tools is now an accepted standard.
So to my parallel, it took a while for digital recording to close the gap with analog recording, but as it did, there were enough pros (cost, convenience) that began to outweigh the con (singular: quality gap), and at some point people began to jump ship and switch from analog to digital.
I feel that the same thing is happening with amp modeling to an extent. Given the limitations of my particular recording situation, I felt the pros of the PODxt far outweighed the con and I made the jump. Some people nod, some people scoff. What's new?
Honestly, I'll probably layer the POD tones with real amps at the end of the day, but in the meantime the POD is great for what I need it for: developing ideas and recording them satisfactorily.
And the beauty of the POD is that, thanks to the exchange of ideas in forums like this, the gap is narrowing. With enough of us monkeys banging away out here, one of us might write War and Peace and get a truly pro tone out of a POD soon.
My gut feeling is the technology will require a few more generations of development, but at some point, it will be very close to the real thing. But for right now, sometimes good enough just has to be good enough and you gotta damn the gear torpedoes and roll tape -- or hard drive.
We get so caught up in our own gear-obsessed minds, that we lose sight of the big picture:
About 0.00000001% of Earth's population could give a flying crap if the guitars are a little fizzy or whatever. Plenty of great, influential, and successful albums have crap production. It's not an excuse to be crappy, it's just a fact.
IMHO, the PODxt is good enough (see above) to allow a good song and a good performance to come through.
Damn. Sorry for the rant. I really do agree with you guys that the POD doesn't sound as good as a real amp! Haha.
