Distortion + low volume fuzzy sounding (not good)

Do new Dist +s sound fuzzy w/ low output? I built a DOD 250 based on the GGG schematic and it sounded great. I just picked up a Dist + and it does not. It had a burned 10k resistor (r9) which I replaced, but it still sounds like a fuzz w low output (barely unity with the pedal turned all the way up). Is there something else that could be wrong, or do they just sound like this out of the box?

Yes Chrisq206, do that. The best way to get help in this kind of issues.

And it sounds to me like there's too much gain in the circuit, or bad/wrong caps not filtering what they should...
A long way is the sum of small steps.

So they're not supposed to sound that way? I wanted to be sure before I started trying to fix it. If someone could let me know, that would be great.

  What value output pot ?
  100k...because the output of this unit isn't all that boosted.
  The output of the DIST+ is directly controlled by the clipping diode threshold voltage, nothing above X gets past them [if you used Ge clipping diodes, an Si will increase output.
