    in theory, could i pull this trick off with a buncha messy connections and a 6PDT toggle switch?

    as sighted in legacy version of dr phybes build guide:
    MOD3:
    For a more Vibe sounding circuit change the stock values as shown below.
    R17 – 100k originally 150k for phaser
    C2 – 6.8n originally 47n for phaser
    C3 -10n originally 47n for phaser
    C4 -220p originally 47n for phaser
    C5 – 2.2n originally 47n for phaser
    C7 – 10u originally 22uF for phaser

    Yes.  Each of the 6 poles would control one of the components that need to be changed.  Each of the “throws” would choose one of the two component values.  A lot of wiring to be done!  I suspect a rotary switch would have six wafers and be quite tall.  I haven’t seen a 6PDT toggle switch.  Did you find a source for one?The two positions may cause some switching noise as well.

    Yeah, I’ve done this before and still have it. You may get a different result, but for me the sweet spot on the trimpot is lost each time and needs very slight tweaking. Switching between songs would be chancy at best to me. Let us know what you come up with. I searched ebay just now and quickly found a 6PDT switch. That’s probably the one I used.

    I recall years ago, that Tonmann suggested switching a resistor value along with a change in clipping diodes for example to compensate for the level changes.  The Rototone Deluxe was inspired to enable just such a simultaneous change.
