Should you be learning on an acoustic or electric guitar? The answer is both have benefits and disadvantages. An acoustic will build essential finger strength more quickly, but that also means it is more difficult to play - especially on a beginner's instrument - until you cross a strength threshold. On the other hand, the strings on an electric are much easier to fret, making for faster playing progress but translating those skills to acoustic more difficult. For either type of instrument, I recommend starting with lighter strings. Lighter strings generally do not produce as good of a tone, but you can move to a heavier gauge once you get some callouses. For acoustic, I recommend starting with a string gauge of 10-47 but no heavier than 11-52. For electric, use 9-42. Coated string reduce noise from moving your fingers on the strings and last about twice as long, but they are also more expensive. The choice is up to you.
