Great playing Willy, God bless you! Thank you for your testimony for Jesus :)
I guessed A for this reason: sometimes it sounded clearer and sometimes not as clear. As in, I heard more dynamics from your fingers if a string was hit harder or softer. Sometimes on the bends, depending on how hard you hit, the tone changed.
B was pretty constant the entire time and a bit 'overproduced' C sounded more like a POD modeling amp to me. That is cool all three were still pushing air, if you did a line out on digital it is easier to tell because they don't have that 'live' sound.
To be honest though, I think I preferred the tone of C - even though I am a tube guy that switched from POD a while ago. C was clearer. But again, with A I could hear more of your fingers playing.
