Hey guys! I'm needing a bit of help, since I'm a bit too far away from a music store to be able to try these out, which is what I would normally do, but wanted more of some opinions and see if I'm missing something. I'm looking for an overdrive pedal for my bass. Just something to add a little bit of dirt. Nothing extravagant, just simplistic. I've been looking for something that does NOT have a tone knob. Thinking about the dod 250 preamp overdrive, the mxr distortion plus, or something that's volume and drive knob only. Any other suggestions? Also I was wondering about the mxr micro amp. Would that give me any dirt or just boost the signal? Thanks!
