I just tried the DOD 250 for the first time at a gig last night. Tone wise, it seems to be what I am looking for allthough I still have to play around with it. The only issue I have (any 4X10 w/tweeter users out there feel free to chime in) is that there is a noticeable hiss with the pedal on. This even is present with the volume on the bass off. I might try to turn down the HF attenuator on the back of the cab ... I didnt expect this because I used a DS-1 Distortion and didnt notice any hiss whatsoever. Is this normal or do I possibly have a bad unit?
