Phaser Advice

[modsquad]

I am starting on the Ross Phaser and would like to build it so that you can switch between the univibe mode and phaser mode.  I have looked at a couple of posts here but can't find how to do it.  I know I can use a spdt switch for the vibrato mode but can I use one for switching between the phaser modes.   Inquiring minds would like to know.

You must use a 4pdt switch.
Here is an instruction on how to wire it:
