I keep my knob at 9 o clock.
The stock Phase 90 will do the job, but doing the R28 mod to it will get the effect sweeter and closer to the EVH sound you're excpecting out of it.

I did the R28 mod and it made a big improvement. It took awhile to take that damn pedal apart cause im an idiot. make sure you take the rubber knob off and unscrew the screw under it.
