This is a 1590BB Pre-drilled enclosure. It has holes for four 1/4" jacks on one side, four 1/4" jacks on the other side, four potentiometers on one end, and a 1/4" jack and DC jack on the other end.
This was drilled for a projcct for two of our Blender circuits to work in stereo with a expression switch on the single jack but can be used for a number of other projects. If you
are interested in building the double Blender, we will certainly help you out.
The enclosure is a little scratched up on the bottom but could easily be smoothed out and painted.
