So my brain thought it was a good idea to have an acoustic guitar, a harmonica with a holder, and an MP3 Player active at the same time for morale reasons and reading.
A tip though. See that icon above your character’s head? That’s the deafened icon. MP3 player deafens the character to the sounds in the world around them so technically should only have that morale from the MP3 player.
If that’s how it actually works in that situation though… <shrug>
I’m just imagining a dude with the whole Bob Dylan setup just haphazardly playing away because he can’t hear since he’s listening to new age speed polka on full blast in his earbuds.
