I have an Atomic Amplifire pedal arriving this week. In addition to test driving the amp modeling, I want to try to use it in 4CM with my EVH 5150 III 50 watt as an effects only processor. I am also going to try using the preamp out of the EVH 5150 III with the power amp only models, cab sims, & effects. Any current owners see any limitations or challenges I may run into in these scenarios? I am a midi noob so I am wondering if I can use the Amplifire to switch channels on the EVH 5150 III given it has MIDI as well?
