Hi mykesbass, yes it has a 9v battery in where the tone,volume pots are, also there is a little black plastic box with 4 small sliders on it, on the box is the name/word KOCH,and just underneath it say's BPA, there are 3 control knobs on the bass, volume, tone and pickups? The pickups are not soapbar size, more like the width of jazz bass pickups,there is a toggle switch also, could it be for active/passive? Quite a difference in volume between each position of toggle switch.
Many thanks,herman.
