It is harder, but not impossible. The Behringer Vamp was basically the POD 2.0 code, tweaked a bit. The HX Stomp does look pretty cool, and I could see considering one, one day. Judging by how the Mooer Preamp Live unit EQ matches other preamps, I have a feeling they have 3-4 basic amp "models" for clean, light gain, heavy gain, etc... and then they EQ match the frequencies of different amps. I have 4 of them, and the Radar, and I feel like they have similarities in feel, but differences in EQ.... like the same thing as if you ran big EQ pedals before and after distortion, and you fine-tune tweaked them to match other sounds.
