Have you studied any theory though? How can I recognize the scales and their names if I didn't?
I had 1.5 classes on it and what I learned can't be applied because it was so basic that tablature still taught me more. You can learn scales without knowing theory, because there is a pattern to scales, and because tabs use numbers, you can use the patterns to determine the spacing between the numbers.
Let's say we start with the first fret on the E string of the guitar on the guitar, and I want to play a minor scale all on the same string for a whole octave (an octave is where a scale starts and ends). The minor scale just has us start at the 1, then to 3, then 4, then 6, then 8, then 9, then 11, then 13. Hitting those frets successively means you have gone through the minor scale based off the first fret.
To transpose that starting at the 2nd fret of the same string, start at fret 2, then 4, then 5, then 7, then 9, then 10, then 12, then 14. All I did really was add 1 to each fret from the previous example.
There's more to it like taking that same run of frets and condensing it to multiple strings so your hand can stay stationary. This is how I teach myself scales, by using patterns and then applying it to any key (key is the starting fret in this case).
I don't know if this is confusing based on what you already know.
