Guitar Amps

Last week the in laws came back for the Cheng Beng prayer. One of my nieces brought along with her a guitar to play along with my eldest daughter. My girl on the piano. Unfortunately the guitar sound was too soft to compliment the piano. The guitar was drown by the piano. My girl was asking me what can they do about it coz our piano is the acoustic piano where we can't adjust the volume. I told them, next trip, get your dad to buy for you the guitar Amps then your guitar sound can be louder. :)
