Best tone of the amp simulators/modelers I've tried. MAX version has a good collection of captured amps and cabs. User interface is maybe not the best possible, but serviceable, especially since there are not any complex routing options here. Only gripe is that they have probably intentionally left modulation/time-based effects out, so that they don't not completely out-date their Amplitube :-) Basic reverb/compression/noise gate are available, which is nice.
