Agan, the volume is a master, My suggestion is wiring it like a G&L S500. (Leo Fenders final guitars). If you need a schematic email and I will send it. The S500 uses a single treble control, and in place of the second treble on a strat, uses a bass control. It also uses a toggle switch to make it possible to combine all pickups or the neck and bridge pickups which you cannot do on a standard strat.
