PLAY TECH 7 BAND EQUALIZER PTEQ. This is a used item, so please check the condition in the photos. Please understand that this is a used item. I have confirmed that the power turns on, the sound changes for each band, and the volume changes with level control. I am not familiar with the specifications and do not know much about it, so I am selling it as is, as junk. Everything is shown in the photos. The batteries will need to be provided by the buyer. The condition is not bad as shown in the photos. First come, first served. How about it?
