I built a push-pull amp. 6sl7 phase inverter and 6v6gt tube. When i push the preamp gain to is maximun ( guitar distortion ) i'm not able to control the volume. I turn the 1 meg pot a little bit and the amp is very loud.
Should i upgrade to a 2 meg volume pot or what else i can do to reduce my peak-to-peak voltage from the preamp ?

The distortion you are getting is because the amp is overloaded, it's trying to do what it can with the large signal you are giving it. Once it starts distorting good, there isn't much you can do with a volume control on the input side. (Giving it a signal larger than one it cannot already handle isn't going to magically make it work.)
