There was some talk a long time ago about implementing that, I have no idea what came from it!
(From the first post in this thread, I did get the impression Greg was asking about simple presets for the existing EQ, just as shortcuts to quickly get in the ballpark of a certain sound image. Maybe it's a semantics thing: I think of "presets" as nothing deeper than pre-saved combinations of certain settings...)
Well, re-reading it it seems truth is in between.
"Different Amp EQ Types or, at east, some presets taken from real amps"...
where, of course, the tone controls mimic the interactive behaviour of their real counterparts.
