to give the vocalist more credibility as a musician?
maybe he's learning to play but not confident enough in his skills so he doesn't plug it. if that's the case, kudos to him for trying to learn
I think its better for a vox to carry a tambourine instead instead
bakit naman? bakit di maganda sayo tignan?
come to think of it, when i watch gigs, i never actually noticed if their instruments are plugged in or not
i just listen to their songs. as a guitarist myself, i look at their gear, especially sa mga pedal board nila, but never kung naka saksak ba mga gitara nila or tumutugtog ba sila.
