This is my second recent attempt at a new amp day - the last didn't go so well - I had a Mesa Roadster head and 2x12 recto cab, which i ended up having to send back, because it was just too much to use in the house, and I wouldn't get the best from it.
With that in mind, I went back to the drawing board. I tried a bunch of stuff, including Mesa's Rectoverb combo (not enough tone at low volume, and not versatile enough), various Marshalls and small Engls, and came up with...a Mesa 5:50 Express head and 2x12 Roadster cab (much smaller and lighter than the Recto).

First impressions are very good indeed. Sounds are much easier to dial in than the Roadster, it sounds much better at far lower volumes, and the 5 watt drop-down switch is a real bonus for getting some nice power amp distortion at low levels. The contour control is great - it's apparently a knob version of Mesa's 5-band EQ set in the V-shape - and it make a massive difference to the tone. It's footswitchable too, which is an added bonus.
Haven't had much time to test it out yet - I've only played my Tele and PRS Tremonti through it so far, but based on those 2, everything I own should sound great. I had been wondering if it would have enough gain for the more metally end of my playing, but I neednt have worried - there's plenty!
