I'd have to get a pickup since it doesn't have a plug.

does it have an on-board tuner like this? if it does, the cable input is right next to the strap lock at the bottom of the guitar. you don't have to get separate pickups

Oh, hers does. Mine doesn't. Sorry.

oh yeah, thats what i'm talking about
as for the singing, i really don't have any input
the only thing i'd suggest is to sing louder on the lower notes or softer on the higher notes. it seems like her voice is fading whenever she hits the lower pitches
(*hint* get a mic)
