I used to own both the Jim Root Terror and Mini Rectifier, but I sold both this weekend... For home use, they are just too loud. My EVH 5150III 50w actually sounds much, much better than these two bar-stewards at low volume levels, but the EVH is just sick. It sounds almost exactly the same at every volume level! One of the best amps, if not THE best amp I have ever owned. For some reason EL84 tubes just sounds "small" and lacking in some way to my ears. Maybe it works better with EL84s in lower gain amps, but for metal you need more power and bottom end, and less power amp distortion to keep it tight. The JRT is never tight though, but with a boost in the front it is usable. The Minirec is not especially tight either, but at least more tight. That amp could also use a boost in the front. Not to bash the thread or anything, but this is my experience (unfortunately)...
I sold them both to fund a Line 6 Helix. That is just one badass piece of gear! Got it home last night to try it, before I buy it. I strongly recommend you guys to try it if you get the chance! I am convinced that the future is digital, and valve amps are really outdated. They are heavy, way too loud (every amp with more than 1 watt) and quite limiting tone wise. But now I am going off topic, sorry for that. Peace out, hope you got a little bit wiser from my little speech here!
Edit: bar-stewards, nice....
