My grandmother had a similar electric organ when I was growing up and I kinda of always wanted one. My neighbor down the street was giving this one away so I couldn’t pass it up. I just had to clean the contacts on some of the keys. The pedal is for volume. 11 voices for right hand and six for the left hand combine as many as you want to. 4 rhythm choices, Latin, rock, swing, and waltz combine them together and there is a speed slider as well as a separate volume slider. There are also “genie” chord selections for the far left keys and a sustain slider. There is a huge speaker in the body of this thing.
