Guitar volume slider

I'm new to the app and learning guitar. It would be very helpful if the chord volume was specific to the instrument you selected or if you provided another volume slider that allowed you to hear the specific instrument you've selected. I'm trying to pick out the strumming of chords on the guitar in the music I'm trying to learn and the chord volume, sounds like a piano, doesn't help me to understand how the guitar shouls sound in the selected music.
