the amplug2 is marketed as having "analog circuitry". that would suggest it's not a modeler.
but, if it is a modeler, and i'm buying one model, i'd be better off getting the amp, obviously.
it's less that i'm worried that i bought one setting on the amp and should have bought the amp and more that i'm concerned that i bought a setting on a modelling amp and wanted a dedicated circuit.
if it's just a setting, i don't want it at all...
