Recognizing melodies by ear is a hugely useful skill, but I can't help but think it's going to be nearly impossible to do without a sound foundation in music theory. Tabs are, in large part, paint-by-number. Lots of guitarists out there are only interested in learning a song. Regardless of key, mode, or what the notes actually are. And, tabs satisfy that group by saying: "Play this fret on this string". To write tabs…

Knowing the theory certainly makes the process faster because you'll recognize patterns, but you can definitely work through most songs without knowing anything about music theory. Just pick up your guitar, slow the track down and try to reproduce the tones. Back when I first started playing guitar, my teacher had me transcribe…
That is not productive. Sure, you can do that once or twice. But it gets painful quickly.

I firmly believe it is a prerequisite. Just by knowing what an interval is and playing that repeatedly, trains your brain to recognize it. Specifically 1-3-5 interval range.
