Over biasing a tube is just a great way to red plate the thing and destroy it. Under biasing is pretty harmless. It can be used as a sort of tone control in how the distortion transforms lower frequencies to higher ones. Audiophiles certainly do this and debate it. It's the reason a lot of people like SET amps with their robust even order distortion and holographic mid-range.
Over and Under Biasing as means for tone control
What is the word about using bias as tone control?
First what is the risk to Tubes and equipment by doing that?
Second what is the actual effect of doing that as far as tone?
I know in the Guitar world it is not uncommon to do, but Guitar Amps are going for shades of distortion, unlike HiFi listening amps.
I would be interested to hear what people think.
Thanks!
