Absolutely! You can learn to play any 6-string guitar with Simply Guitar.
When you play with an electric guitar, make sure you...
Play with your amp directed towards your device.
Play without any distortion.
And... That's it! Enjoy!
If you happen to switch between Acoustic or Electric it's totally fine, the app will recognize your notes regardless and you do not need to change any settings.
