Yeah I agree, but keep in mind not everyone is after trying to copy Robben’s tone. For example, I personally gave up chasing other people’s tone a long long time ago. That’s not to say I don’t have a EVH or Adam Jones Patch or something close to it, but my main focus is creating patches/tones that are “my tone.” And as such, I have no real “rules” per se
. I use my ear and the knowledge I’ve gained over the years & years of playing & listening & reading etc. I certainly don’t claim to know it all, I’m always trying & eager to learn more, I love it, and also always willing to share & pass whatever experiences & knowledge I’ve come across along as well. That’s the one cool thing about a unit like the AFIII, you can crank the MV and not blow your ears out, or have to have a load box. It’s just another tool.
I will say typically MV amps do generally sound better with the MV lower, but there are definitely some cases where higher settings sound good. Especially on a lot of the clean channels, if you’re looking for a bit of grit, compression & fatness. Thickens things up, get a bit more sustain & more mids.
Each amp is different though, but I always try and “learn” how that MV effects everything when first dialing in any amp. There’s a lot of good stuff in there.
