All I really wanted to say is that I think this is a cool tool for someone who wants an 8 sec looper and a lot of good guitar sounds. You just have to budget in an EQ if you plan on using it through a full range speaker system. You're right in the sense that when a speaker is cranking away at loud volumes the actual material of the cone is surely deforming in subtile ways that no "modeler" is even attempting at this point. I don't think they are at least. That sounds like a *lot* of math. Math is hard! I'm OK without being that accurate in my little world. What I lack in "reality" with amp modeling, I more than make up for in variety and portability. On the other hand I have to say that with the Tonelab (Probably the Pod as well) there really is an issue. My guess is they made this with the 90% of people who will use it in front of an amp in mind. When they put in the "line" output, they didn't spend as much time making sure the output was appropriate for a full range speaker. I haven't done a frequency analysis as you mentioned, but in a sense I did one when I pulled down a graphic EQ fader at 15 khz and it made a BIG difference. It shouldn't. Look at the specs of a popular guitar speaker: http://editweb.iglou.com/eminence/eminence/pages/products02/legend/ leggb12.htm They spec it to 5.5 khz on the high end because after that there is a pretty steep falloff. It's a natural attenuation of high frequencies due to the physics of not being able to move a large mass fast enough. That's why tweeters are small and often even cooled due to the heat they can generate. Guitar amps don't have tweeters because amp cabinet designers figured out a long time ago that the frequency range of an electric guitar didn't extend that far up so a 10" or 12" speaker was fine. A lot of what you're getting rid of is pick attack and string noise/fret noise. With a high gain pre-amp situation, you're going to generate harmonics all over the place, so the cabinet's natural attenuation of high frequencies is crucial for making sure your sound is "warm" and not shrill. That "warmth" is really a lack of fidelity, but in a good way. So Vox is right in saying that most people who've bought their product have not complained.. but I bet most are using it with a guitar cabinet. Mark
