I've been playing bass for several years, but I've just now become interested in effects. I wanted a pedal that would make my sound a little bigger and dirtier for playing popular rock covers (nothing extremely heavy). I bought an Electro-Harmonix Big Muff, and that wasn't what I was looking for. I'm now looking at either a Darkglass B3K or a Swell B-Pro overdrive. How much difference will either of those pedals be from the Big Muff? And will either of those pedals give me that little bit of boost and dirt without going overboard?
