I have both maxi matchers and an Orange VT1000. I have had no problems with the Orange although I know others have. The Orange is accurate according to the maxi marchers although you don't get numbers with it.
I've used the original VT1000 now since it came out, and have tested a bunch of tubes for my own collection. I write down all the settings and try to match what I have. I used to buy tubes for every new amp, when they were affordable, lol. Not gonna lie, I want this new one. ?
