I believe that it is extremely unfair to acoustic guitars to not be represented in an emoji. Almost everything is represented with an emoji; from DNA to the Solar System, but nowhere in between is there an acoustic guitar. 

Acoustics were also invented between 3500 BC and 3200 BC, while electric guitars were just recently invented in 1932. Therefore, acoustics have been around for thousands of years while electrics have only been around for about 90 years, yet Apple still has the nerve to only create an electric guitar emoji. 

Another serious issue is that electric guitars are terrible guitars to learn off of. In order to tell if the guitar is tuned, or even to see if you're playing it right, it is so much easier to be able to actually hear what you're playing. Acoustics don't require you to plug them in in order to actually make a loud sound, unlike electrics, which don't even feel like real guitars. 

One last thing.... 

"...acoustics are just ✨ better ✨"
