Sahabat Sejati (Sheila On 7 Cover)

Using Casio keyboard and Gibson ES-175 replica. Recorded in iPhone and Yamaha AG06 Mixer. Yes, it's hiss-ing. It happened when we plug keyboard and guitar or mic channel at the same time. If we use just keyboard channel or guitar channel, it's ok. Oh, and we have to so turn down all knob and turn off all effect on guitar and mic channel if we don't use it http://www.nugroho.life
