I am a massive dUg fan, but this is an example of how it can and cannot work for people. Personally, I haven’t found the same thing happen as @attackbass I have been able to get enough dynamics out of it, but we all play differently (not saying I am better btw!), different basses etc. It can stack really nicely with another pedal as well to combine tones, or give versatility at just a click to have the 2 tones described above, as inherently, as described it is a pedal producing a clean low end and a distorted high end, although you can clean it up, so it is possible this can happen.
I have to say with any pedal, but especially the DP3X, the tone knob on your bass is your friend, it doesn’t just have to be wide open or closed, there will be a sweet spot to help the pedal.
