Here's how I envision you could incorporate it into the GUI. You could make another drop-down menu to the right of the one for filter type where people could choose presets. There would be standard 20-band presets that move the sliders. Like I've said, I think these are good for people to use as a starting point. Say a user wants to make it sound something like the real thing, but they just think the treble could use some tweaking, so they select the preset and change a few bands rather than having to manually set all 20 and trying to figure out by ear where to set the other bands to sound the same. Then you could have in the same drop-down menu options that are named the same as the standard ones, but with something like "(High Precision)" appended, and selecting that would disable the sliders and a 60-band preset would kick in.
Here's an unimportant little semantic dilemma I have: what do you name the output method I've been using, the standard white RCA jack. When referring to video, it's composite, but that's a term specific to video. Sometimes people say A/V, but that's vague, refers to video when there is no video aspect involved here, and might be confusing when one preset is "NES A/V" and another is "A/V Famicom". You plug a coaxial cable with RCA plugs on the end into it, but people don't commonly refer to that kind as coaxial cable and instead use that term for the cables typically used to carry cable/satellite television signals that have F-type plugs on the end... like the NES and some Famicom RF adapters use. But only one end of the RF adapters has an F-type connector, the other end on both Famicom and NES is (drum roll) RCA. What the hell can it be called that will convey to a layperson what it is and prevent confusion? Maybe it's just not necessary to say anything and it'll be assumed that output type is the default for systems that have it and RF is the unusual one that needs to be specified. So in this case, the preset would just be "Twin Famicom".
Anyway, here are the 60 values if you're willing to try my suggestion.
