I feel I'm in need of an overdrive as I have two effects that are essentially both fuzz: an original DOD Bass Grunge and an American reissue Big Muff Pi. Which do I get rid of? The BMP is a classic, but the Bass Grunge is far more versatile. Also, I was thinking of getting the Hartke Bass Attack as my OD. Is that a terrible idea? Does anyone have experience with an OD that will sound good on wildly different basses? My main basses are a fretless six-string and five-string ABG. Thanks for the help.
