Hi, I stopped mucking around with my empeg when I found out the product was not being produced anymore. The button modification is easy and the player was actually designed for it. I stopped right before I ran a prototype of a printed circuit board ring with surface mount LED's for the knob illumination. This is not as easy of a hack because you can't run it off the same power as the other LED's, so you have to look else where in the player for power. I'll let you know if I make any more button and/or finish the LED ring.
