YAMAHA Yamaha STAGEPAS Stagepas 300 Powered Mixer For sale. This listing includes the mixer, power cord, and case only; speakers are not included. I have confirmed that it is working, and the sound output is fine. The main knobs also move smoothly, and there is no crackling. There are many small scratches, but there are no major scratches, dents, or chips, as it has not been bumped or dropped anywhere. It's in the usual used condition. The case is not the original one, but I have been storing it in a case that fits perfectly. I will ship it with the case on.
