Did you notice that protestant churches have bands nowadays? I wasn't really used to it because I grew up in a church where piano is the only one that provides music. I wonder if there are churches who still use only the piano. I've visited a couple of churches already and I noticed that they have a different praise and worship time now. Used to be solemn, I am not saying though that it's gone wild today, but yeah. Anyway, I'm sure those churches who have bands have this cool yamaha amp. It helps with the quality of music I guess. Oh I don't really know but you can enlighten me on this as I am not one musically inclined person.
