Sparks guitar effects tutorial

  • Hi everyone,
    Newbie here, not only with Spark but with the infinite world of guitar pedals/ effects. Anyone knows of a tutorial where we could find explanation on what these pedals do and what all the different adjustments do. Even if some have names that say most of it ( like reverb) they are equipped with many buttons that does not mean a thing to me. I know, I could try to play with knobs and I did, but something like a tutorial where pedals are explained and use of the different knobs is also explained would be welcome. I look on youtube and could only find frustrating videos where nothing is explained, just people playing guitar with different effects.
    thank you
