I have the Vox wah. (847 I think it is) I tore it down and rolled the tone pot up some to try and bring up some lows. Now, unlike my usual AR self, I didnt note or mark my starting point, I just cranked it up some and put it back together. Does anyone know where the starting point is? Meaning, if I wanted to set it back to stock, would I roll the pot all the way off?
