got your boards, they play just fine in my KI and MKII cabs. I think its the voltages from your power supply. Just for the record,I like Run and Gun 1 much better even though 2 looks better.
Dip settings, this is how you want them, except dip 4, that's for 2 monitors, you want that one off.

switch bank 2 (aka switches 5 through

don't do anything.
Switch 1 mono/stereo sound
Switch 2 normal/flip monitor 1
Switch 3 normal/flip monitor 2
switch 4 1 monitor/ 2 monitors

so, what do you want to do? Send me your set up and see if I can make it work, or me just send you both RnG boards back?
