Subject pretty much says it all... Was thinking about getting one of these down the road. People seem to LOVE them for live use but I haven't heard any opinions on how they fair under a mic...
I think they are just decent cabs that look like a Death Metal Band would play them.
The reason I'm asking is my buddy Mike Gilbert from Severed Savior uses them religiously, and his rig is an Engl E570 preamp, Engl E850 power amp, Fractal Audio Axe-FX with Evidence Audio and Mogami cables. Dude is an absolute tone nut and he much prefers the Vader cabinets to both his Engl XXL cab and the Mesa Recto cab he used to have...
It is actually quite funny that opinions about certain products are so different on different discussion boards.
On sevenstring.org Orange and Vader cabs are these universally awesome cabs, that are beyond any critisism, and if you dare say anything bad about them, you are labeled a n00b or whatever. And there, Mesa cabs are often said to be boomy and awfull.
I was faced with an Orange inquisition when I bought a Mesa Rectifier cab to replace my Orange PPC412 cab. For me(!), the Mesa cab is the perfect cab. Smooth, tons of low end and very neutral sounding, where the Orange cab has a very dominant midrange. Not a bad sounding cab, not at all, but I think the Mesa cab is way better sounding. I still have the Orange cab, since it sounds very nice when playing certain things.
I have never even tried a Vader cab, so I don't know how they sound like, but it seems there's a lot of hype around them, and a lot of people who have never even heard or tried one of them are praising them. But like I said, I have no personal experience.
Looks like I'll stick with my Mesa cab for now!Engl cab in July I think!
