I've tried a few of the older amps (RG100, 80, Century 200) and I love this one by far in comparison. It's got a HUGE tone and gain for days, even with the 2x12 I'm using. The voicing is a little different too than those other amps, which is something else I like. Even though it's SS, I get a really thick tone, shaped even more with the onboard EQ. I've used the other amps with outboard effects and EQ's, but it didn't have the same kick. The only other SS amp I liked with this chainsaw gain was the cheaper B52 amps, but it still didn't have the thick tone this had. It does have a lot to do with the cab I was running it through (The B52 was going through a Marshall 4x12) and although the basic tone was there, the Randall cab gave me a bigger and more asskickin tone, so to speak. The MTS head is great, but I also love that raw chainsaw tone, so I love it just as much as the tube head
