Sounds like an exciting duo, and I love the influences that you wrote about. I am into a lot of similar sounds, although I also dabble in keys so if I want a really organ-y organ sound that's where I go.
My favorite pedal for this type of stuff is the EHX Superego+, hands down. The main feature is that it acts like a freeze pedal, holding a note or several layered notes depending on settings. Then, it runs the frozen sound through one of 11 effects including delay, echo, reverb, wah, pitch shifting, phaser, flanger, etc. I think that the pitch shifting is basically a POG.
It gets good when you add an expression pedal. Need a wah? Got it. Want to change your delay time and get that rubberneck sound? It's in there. Want to make organ sounding chords that glissando from one to another, with subtle or not-so-subtle trem applied? You got it. Also, it has an fx loop so you can add whatever other pedal you want to affect the frozen sound, or use it as a blend pedal.
It gets GREAT when you trade the expression pedal for a sequencer. I've used it with a Korg SQ-1 and an arturia keystep pro, using control voltage into the expression jack. Program your wah to do whatever you want. Set it up to modulate delay time, change the rate of the phaser, change the delay time, etc. It becomes such a beast when you start to sequence the fx. Also, if you dabble in synths, this thing takes any mono-synth and allows you to play paraphonically. Definitely my favorite pedal.
Hope you'll post some music at some point because this project sounds awesome.
Cheers!
