A 6-channel powered mixer, the YAMAHA EM-70, featuring a retro spring reverb function. It's an enjoyable, cost-effective retro rotary mixer. Above all, it looks fantastic. This was used by my younger brother and has been carefully stored. I'm not very knowledgeable, so I've only confirmed that it powers on. Please refer to the images and make your judgment. Since I don't know much about it, I'm selling it as junk. No returns accepted. Comes with a hard case. - Brand: Yamaha - Number of Channels: 6 - Effects: Spring Reverb - Master Volume: Yes - Input/Output Connectors: Line, Mic, Guitar - EQ: Treble, Bass - AUX Volume: Yes - Output: Stereo Please also check my profile.
