So my dads friend gave me this for my electric guitar, but none of us know exactly what it does. A little help? It’s some sort of graphic equaliser and you can step/ push on the black part.

So that graphic equalizer doo-hicky of yours is pretty neat! So, if you want a clean, smooth sound, i recommend setting all the sliders to the middle. After that connect your guitar to that, and step on it (to make it work), and there you have it! It's like a special "old school" kind of speaker. You can sell that for good money. Plus you can adjust the settings to get the vibe you want.
