This is likely for MJMP:
When setting Master level during programming and output using the front potmeter, we of course will be using the LED's.
But.. how are those LED drivers calibrated? Will they start firing up / blink juuust when it's about getting too hot, or what?
Do the start blinking merely as early warning? Do they light up [almost] solid when it's really resulting in distortion, or when it's just about to?
Looking at especially when the tonestack LED starts firing doesn't match my sonic experience, i.e. I seem to notice unwanted distortion right before the LED starts firing, meaning, I'll have to set levels just a touch too hot to actually see the LED firing, and back off a touch.
Would be nice to see the LED firing up just when distortion is about to start taking place..
Regarding the manual potmeter outputs, I don't see much relation to when I can hear distortion and when the LED starts firing - the LED seems to be more of a simple indicator to how hot the output is, like a poor man's VU meter

Further: I haven't re-checked the schematics, but IIRC, those LED drivers do not feature adjustments for calibration, so, what's the procedure, should I want to?
Obviously, some resistors can be changed to facilitate changing when the LED's will fire..
