The Great Destroyer -- phase question for blend knob

[jonboper]

I want to build a modded version of this circuit for a bass player who likes crazy sounds. To make it bass friendly I'd like to include a blend control, but I know phase is an issue when running signals in parallel. From what I can tell this is a non-inverting circuit, but want to double-check with anyone who cares to take a look.

Also, if anyone has a suggestion for a combo with this that'll surprise and confound my friend I'm open to it.

Here is the chip:

Actually, after playing around with this for a few hours today I don't think a blend knob makes any sense...I love it as is. Maybe I'll mod it a little, but adding dry signal isn't what this needs at all. I still think it wouldn't invert phase, but a moot point. Moderator can delete if it matters.
