I had a JVM410H and it wasn’t terrible, but the gain channels had horrible gain structures. Green wasn’t enough and orange was way too much, even at 9 or 10 o’clock. Red was even more so. And it was significantly noisier even with the gain that low.
I understand you are picky, and maybe the JVM would suit you better, but I find my EVH to sound better and have far fewer issues with noise than the JVM had. Makes a nice alternative to my two Mesa Marks. And I prefer the red channel with the gain around 9 o’clock for rhythms and the blue channel boosted for leads most of the time. I’m only using this stuff for recording, so that isn’t a hard rule, as it changes based on the song.
