Hi,
i just want to let you know, that I build a BG LED mod too. I talked with nodyeliab and he had no problems with that because he is still very busy at the moment. I love his idea!
This mod works a little different. It takes the power from the BG ramp coil. So the girl will be light white when the ramp goes up. It flashes 3 times at start to show the BG mode begin. Flash red and fade to black when hit. Synchron to the synth pin sound. After 4 successful hits, the light (red and white) flashes 3 times to show that the mode is done.
It takes over 1 hour for soldering one board. We don´t make this about the money. My wife and me have fun to make this great machine more better.
We send out 10 boards in germany and the everyone is happy with it.
