I'm from Montreal and i've been on the lookout for a Ernie Ball Bongo 4 string. The only dealer in montreal who carries Ernie Ball products is Steve's music store, and they've been sold out since forever. Today i finaly managed to secure a Dawn Blue Bongo 4 string with a single humbucker. It's reserved and in my name, all i need to do is go get it. My question is: Is a single humbucker model really that inferior to a duo humbucker? What am i missing out on? This is my first big electric bass purchase. as such i am a bit of a newb. Any info you can offer up about the pros and cons of a single humbucker pickup is much help. Thanks in advance!
