To the right and it is much more muted and less dynamic. The Pure/JFET switch didn't appear to make much difference, but to be fair I haven't played with it much yet.
The Z-Tone and Pure/JFET controls are the parts I least understand, so far. I mean, yes: I know about how impedance works, and I know about JFET preamp/input stages on physical amps ... but I don't quite understand the rationale behind the controls on the AXE I/O.
Well, OK ... I presume the Z-Tone is there since many physical amps have high impedance inputs, and you you might want to "crank that up" to get you closer to the behavior of a real amp -- but how would you know where to crank it for, say, "maximum authenticity"? Or is it just a question of "this will change the tone, and set it where you like it"?
With that in mind, the Pure/JFET control seems essentially to be giving you the option of putting an extra stage of dialable saturation in front of Amplitube's gear emulations (or whatever the AXE is feeding). And, yes, that is an extra tone option ... but why?
I'm sure that there are practical reasons for these things; I think I may just be unfamiliar with them. But I'd like to know what the intentions are.
