Hi group, as REv has mentioned ( and thanks) there is much to be learned about the GNX4 and it can blow away any other modeler hands down. The shrill probs some are having..turn the speaker compensation switch on and always leave it on. I have resampled the models and added many many more by recording live amps and sampling through RTA and other equip. the results have been amazing as many would attest. I have a site dedicated to the GNX usage and other details if interested.
