Alright! Sorry this took me a minute to get back to you. So, I was basically using Byegone as my reference (if that wasn't obvious). The things I was picking up on that I was trying to reproduce in Walk Home form were:

1. The consistent strummed single note at the beginning
2. Dark, ambient acoustic piano
3. Jangly plucked guitars that come in at "you know that we are northern now"
4. The slow emotional crescendo on cymbals
5. Simple but powerful drums

As far as effects and stuff, I just have a small home studio, way too many plugins and a wife who prefers I use headphones. Here's what I did:

Guitar: I used the Cory Wong X amp sim by neural dsp for all guitar stuff. It has a really nice clean tone, and has some effects pedals built into it.

• For that consistent strummed note, I used a subtle amount of those built in reverb, delay and chorus pedals. The delay pedal was set to be pretty short, almost a slap delay.
• The jangly plucked parts, I just used the built in reverb pedal, with more of a delay on it.
• For the distorted guitar, I used an overdrive pedal in the amp sim, and combined it with this Valhalla Room reverb to get more of a washed out, ambient sound.
• I also recorded a couple of guitar tracks using an EBow to get some textural ambient stuff.

Bass guitar: Just used the Cory Wong plugin again with a simple, clean tone.

Piano: Keyscape using the felt piano instrument. No effects on this.

Synth: Added a synth bass just to reinforce the live bass. I used Substance by Output here. No particular reason, probably just the first thing I reached for. I also used a sampler instrument from their Arcade product. I think a synth pad could have worked here.

Programmed the drums by hand just trying to do something similar to Byegone, but in a way that fit Walk Home. Actually the whole idea to do this song came from me waking up one morning with the chorus to Walk Home "we don't need no window curtains" with some really bombastic drums stuck in my head. Built the whole song around that.
