This is Klipton my DOD 250 or MXR Distortion + clone. They are super close to the same pedal if you did not know. The "distortion" in the name really is a not accurate. DOD calls is a "Overdrive Preamp" which is a lot closer to the truth. This a pedal that uses soft clipping which sounds different than the Tube Screamer family of OD that most guitarist think of when they hear the word "Overdrive." If you want OD but want to something that is a little different this might be a good choice for you.
I chose LED's once again for clipping diodes. Try different diodes and combinations and pick to taste. A lot of people seem to like add a third diode It is a cleaner sound non fizzy sound. The pedal cleans up nice when you roll off the volume on the guitar with the LED's it almost becomes a clean boost. You can get a lot more volume with the LED's as it does not clip as much. The other thing you might want to try is changing the input cap value. I stuck with the stock value but what sounds best really is dependant on your guitar and amp.
This pedals is great for bass players also. A lot of them including me dig it for bass.
It is a very simple build with low components count.
