    What is the atinutiation (sp?) knob for on the back of the PF 115HE cab? In other words, what does it do to the sound?

    So which is the "all the way on" seeing and which is the mid setting?

    You can tell by using your ears, but all the way to the right is on all the way and all the way to the left is off. That leaves the middle position, which, believe it or not, is the middle setting ;)

    ANd normally I would have just assuemd that. HOWEVER....."off" sounds liek the horn is on when I play, as I don't have as deep a tone. Hence the question.

    If you can't tell a difference, your tweeter might not be working.

    You shouldn't have to ask this. It should be quite noticable.

    No, I CAN tell teh difference when I change it. I just want to make sure that "off" on teh switch indeed mean's "off". The whole "0 db" on teh full right position throws me off as well.

    In recording terms, 0db on a recording console is where clean sound ends and distortion begins, so 0db is often considered full-on. The -6db on the middle position means the tweeter's output is being cut by 6db. Forget what the off position says but I think it says "off" ;).

    That's just it. It seems the oposite on mine.
