oh in that case just remove the part where it says
Options.SFXVolume = Options.MusicVolume
then the sfx volume setting in the main menu will control jingles independantly of music and sfx

@☢ Nato Potato ☢ This is good, thanks! Now that I'm thinking about it more, I am interested in like a Jingles Slider, you know? That way you can have Jingles be its own customizable sound, separate from Music and SFX. I'd do it myself, but my coding experience is a bit...mediocre at best, haha.

good idea, personally I kept sfx low rather than off so after seeing this I was thinking of a way to do it that wouldn't require editing audio files, had an idea to use a repentngon callback to filter sfx and adjust their volume before they play, allowing a customizable volume setting rather than just silent, threw something together real quick and it seems to work fine on my end, feel free to use it for your mod if you want, (just as a main.lua file, no resources needed) pastebin com/rV6vwVBf
