I'm thinking of picking up either one of these amps and I figured I'd ask you guys for your opinion and past experiences. I have a Tube Screamer and a 10 band MXR EQ that I'm willing to use with any one of these guys but is one amp better than the other? Does the Century 170 have more gain on tap than the RG100ES? Whats the difference between the Century 170 and the Century 170 MKII? So I ask you, Gods of Mayhem, which one will suffice my need for bone crushing CHUGGA CHUGGA brutality?
