... this is something I never do. Ever. I've never done it to prove the control will go that far but the most I ever go is 3/4. Often I'm playing with the bass control at mid point or backed down. Note the preamp in my 'Ray has some bass & treble boost built in so mid point is not flat. I suspect when I turn it down I'm getting it closer to flat.... turn up the bass all the way on your bass guitar
But full bass (or treble) boost? Never, not me.
