I hear you on that one. It took about 4 hours just to do the button LEDs.. I was all jazzed to get it going! The biggest pain was clearing the through holes for the LED leads (they were filled with solder). Thank god I had good assembly tools at my disposal (vice grips, fine solder tips, etc.) After looking back, I see how it's easy to be off by 1 pin given the configuration.

Now I need to fix the freakin transistor on the knob PCB. I think I blew that puppy out too.
