This gets repeated a lot. It's a good mantra on anything with settings. I have had great success with this when recently re-doing my band presets after swapping from the II to the XL+. Just play, turn knobs or push buttons until is sounds best, save. It almost becomes a fun sort of suspenseful game seeing what you get. For example, I wanted to put a drive pedal in front of a Maz 38 amp, and would normally pick the tried and true TS808. But selecting by ear alone, I ended up with the Eternal Love pedal... the Lovepedal Eternity model. I have never played this pedal live, never even seen one in person, and would have been very unlikely to select it in normal circumstances. It sounds so good the other guitarist in my band walked across the stage to ask what it was the first time I used it live. That, my friend, is what you want.What does it matter? Close your eyes and adjust them until it sounds good.
I started to get far better tone when I stopped trying to emulate other people's knob settings and just starting turning the knobs and listening to what sounded good to me.
If you really need to know the Drive and Presence are within the tolerance of the pots. The MV may or may not be the same. The Axe-Fx II uses the same taper for the MV for every amp model. It doesn't matter though. The important thing is to understand what the MV does and learn to hear its effects. MV controls the power amp drive. At low levels the power amp will be operating in its linear region. As you turn MV up the power amp will start to distort. A little power amp distortion makes an amp sound better that's why amps have a "sweet spot". When you hit the sweet spot the tone gets smoother and the amp gets bouncier because the power supply is working harder.
You will get far better tones if you concentrate on learning what the knobs do and how they affect the sound than mindlessly copying amp settings off a video or forum or something.
After reading your post I tried out the Eternal Love pedal. Very nice! Really can't decide whether to use this or the TS808 mod now.This gets repeated a lot.

Trust those ears. I'd bet the model is as close as one 5150 III amp is to the next.
What was your sweet spot you choosed there for the Red channel defaults " 4" on the real Amp then? Would be interesting
MIMO, the sweet spot of the MV depends on the current Drive adjustment...the more drive, the more power hits he input of the power amp section ... so, it is variable ...and interacts eachother...

Would mean you can't translate the default value on the MV to the real amp or a certain spot because it depends on the Drive setting before,
How precise is the Axe fx II 5153 Red parameters of Drive, Presence and MasterVolume in FW 19 to the real amp actually, are they different at same positions??
