I had a TriAxis/2:90 rig for a while and while it was definitely cool, it sounded kind of 2 dimensional...especially after selling my early Mark IV to get it. I ended up ditching the rack rig and bought a Savage 120. The Savage is a beast of an amp and sounds incredible, but I really missed that low midrange growl of a Boogie, especially in a live situation. I ended up letting it go after a few months and went back to Boogie. It seems like no matter what I try I always come back to Mesa. If you're interested in a Roadking, I'd really recommend a Roadster. Of all of the high gain amps I've had over the years it's by far my favorite. The Roadking is an awesome amp, but it has so many features crammed into it that it kind of loses its 'organic' qualities. There Roadster is more stripped down and to the point, but still loaded with lots of great features. If you have the opportunity to check one out I really recommend it. I get picked on a lot for being a bit of a gear whore because I tend to not hold on to things for long, but I've been rocking this thing for almost 2 years and am really happy with it.
