It's actually really funny you bring up Sword and Ice. I initially had it as a bonus track, something recorded with the Violin, Harmonics, and a 12 string acoustic running through my Fender twin's clean and a pedal called the CP-508, an ambient "wonderland" style pedalby the company Caline.
This version of the track also has some Mendini Glockenspiel which I mic'd up and ran through the same CP-508 pedal, right in the pre-bridge sections.
The difference in the tracks is the mixing mostly, but the version in the OST has the overall guitar feedback sound I wanted to experiment with and went for. That's what inspired the restructure of the track, adding a third segment to let the feedback have more space to loop.
You can listen to it here - https://turtlebox.bandcamp.com/track/sword-and-ice-isolated-strings It's a lot more straight forward and doesn't trip over itself by trying to have a ton of different tonal sounds coming in and through. I hope you enjoy this one a bit more, but regardless I would love to know what you think of this version.
EDIT: Here's a demo of the pedal on amazon - https://www.amazon.com/Caline-Wonderland-Ambient-Modulated-Aluminum/dp/B0B2BXG7B... Caline is a weird brand, not really known for anything but knock-offs, clones, and cheaper pedals. I like the CP-508 because it's decay is insanely aggressive and in mixes like this it really just kind of sits back and gives that Supermasive type of wash without being super up front in the mix.
