Amp modelers don’t quite understand two [other] things: they don’t understand the impulse of the note, so they don’t quite get the contact with the string correct - the way a tube goes ‘whoosh’; what I call the ‘wapoosh’ of the note. Amp modelers don’t yet know how to take a note and squeeze it the right way and send it out.
Second thing is, there’s a lot of harmonic artefacting taking place if you play more than one string at the same time.
Like if you do one of those bends where you’re playing three notes at once - you’re holding two, you’re bending the third one - it just goes [makes digital noise] on top of it because it doesn’t quite understand how to translate all that: three different notes of harmonic information, it just freaks out. But it’s pretty close - it’s not bad!
