[sdiy] electrical problems with panel pots/electrical tape

[Dan Snazelle]

thanks a million

i will start using two nuts AND rotating as you said.

what i dont get is why the holes WORK if they are not suppose to.

i guess it is cheaper than electrically separating them from the pins? 


its funny when i first bought them, i thought WHAT ARE THESE STUPID PINS FOR? and i just assumed the HOLES were were you were SUPPOSED to put the wires...at the time i did not understand what pcb mount meant


oh how much  these months have taught me (thanks to y'all)

BY THE WAY CARL CRAIG WAS AMAZING TONIGHT AT CIELLO. makes me remember why i am making these machines!!!!!!!!*************
