Hola Sally
Likely he will need to bring his own small amp and extension cord (if not battery powered) as they only have been using a single input small amp. If he is anticipating playing at an open mic and/or somewhere else he may be able to hook up to the amp there. It never hurts to come prepared.

Most people bring their own acoustic guitar, ukulele, drum, harmonicas, flutes etc. Mike and Myranda provide a variety of percussion instruments for those who wish to participate but have no instrument of their own. Music binders are provided but feel free to bring your own songs to share. Otherwise, lend your voice to the Sunday Jam. All are welcome

They will be putting an announcement on this message board after they have arrived, moved in and are ready!
