when I set up a pedal to run at 12v is the bias now 6v? Or is it still 4.5?
Depends what pedal it is and what's being biased.
rump roast, jfet.
Yeah should be close enough.
I actually chunked the meter. It was too distorted. I biased by ear. Took some output away but is cleaner. I don't use it that loud.
