Guitar Gallery is the proud agent and reseller of Acus Sound Engineering and we will be launching these at the SA Guitar and Music Expo 2018. We have been searching for a natural sounding acoustic amplifier and Acus meets our requirements. These amplifiers have multiple channels (2 - 4) and allows the musician to plug in his/her microphone and guitar and entertain the crowd. Our models include: 8 inch, 6 inch, 5 inch. We also have a unit called the "Forstreet" which can run on an internal battery for 7 hours!
