I've tried a couple of bass overdrives, and couldn't get a fuzz to work well for me. I had the ODB-3, but I couldn't manage to tame the right amount of drive through my chain. The Blumes is the perfect solution. Three modes, all different, one heavy overdrive/distortion, one relatively smooth light overdrive, or clean signal, and one heavy (but still smooth) overdrive. I like it on position 3 with everything turned to 10:00. Very versatile and easy to use. You can get a lot of sounds out of this.
