I have a dean metalman ML which I use with a Behringer SF300. I have no amp, but I'm planning to buy one soon. I want a distortion(or overdrive, or muff etc) AND wah wah pedal (2 in 1) that will operate with my bass. I have used some other guitar wahs, and the did change the overall sound, but that was all. the wah had no other use no matter if it was on the move, or on heel position, or fully pressed. I want something that will have use
