I'm still working on mine, I had a little setback and had to put them on the shelf for a while
The guy I split the set with made a 9v batt box and changed the lemos out with 1/8 inch jacks...worked well, but the sound isnt any better than a pair of CSBs. Although he built his battery box with stuff laying around his dad's shop...need to use better components
we made one tape that got erased on the ride home
