I'll start off by saying that I love the axe fx2 and especially V10. Before V10 I was falling in love with that 5153 RED channel but afterwords it sounds weird. this is kind of ridiculous to say, and may actually be a testament as to how good FAS has gotten at emulating true tube amps, but that amp sounds like it has a bad tube haha. There are a bunch of great sounding amps, and specifically I'm loving the Euro Uber in place of the 5153 RED. I just found it more amusing than anything that an all solid state tube amp emulator sounds like a great tube head with a tube going bad. Made me kind of giggle haha..
