Hi All, Seeking some advice. I have a couple of NMV amps that when cranked into a reactive load exhibit this weird, grainy, almost harmonic that sits on top of the notes/chords played. Is this just ghosting and because I'm so close to the speakers it's really prominent to my ears? Or is there something else going on? I've tried to provide some examples below. I used a looper to ensure that the exact same thing was played in each example. The first example is my Power Station with a mic used on my speaker cab: The second example is using my Suhr Reactive Load and IRs in my DAW: On the chords you'll note that graininess sitting on top, and when I play the single note you'll hear that whiney, almost harmonic sitting there. I've noticed that it is more prominent when I'm using the neck pickup and less prominent when switching to the bridge pickup. What I've also captured for reference is the noise that happens from the tubes on the amp. In this clip I'm using the Suhr Reactive Load and my studio monitors are off, so all you're hearing is the noise coming from the tubes/back of the amp (the Suhr Reactive Load also makes noise, but this clip is mostly the amp). Am I going crazy hearing this noise? Is this normal, or is there something else causing this? Any thoughts would be most appreciated.
