I just picked up the Ampeg Scrambler OD pedal. This pedal kicks ass. To all of the people that are wondering if this pedal is worth the $230, stop wondering. At least give it a shot. I have tried the EH Big Muff Pi and was left wanting. I tried the Ibanez Tubescreamer TS-8, and was unsatisfied. The Boss ODB-3 is a great pedal for guitar-like bass overdrive, but not warm, fat distortion tones. If you want your distortion to sound warm, like Tim C. from Audioslave/Rage Against the Machine, then give this pedal a shot. I do not experience any muddiness, at least none that you get from an overdrive. My plucking is distinguishable and fat. Plus, it is true bypass!
