would a pull down resistor help? if so where would i put it? and what value?

Yeah, the polarity switches pop. I never bothered trying to get rid of it since it's not something you'd be messing with while playing. I suppose you could try putting some 1M resistors in parallel with the switch poles, that might help. It would be two resistors on each switch, one connected to each outer lug with the two joined together at the center lug. It would be worth a try.
