That's my take on MXR Distortion Plus. I had built one before a few months, but i didn't like it. So I took it apart and rebuilt using Dragonfly's veroboard schematic, but I couldn't make it work. I checked it with a schematic fron tonepad.com, and I found that it misses a trace cut to the right of the 1u electrolytic cap. I fixed that and now it works great!
I'm pretty happy with the result. The distorted sound is pretty good and with enough gain. But it's a little more "trebly" for my taste (Maybe someone could help me change something in the schematic: http://www.tonepad.com/getFile.asp?id=115 (http://www.tonepad.com/getFile.asp?id=115) to make it more "bassy" ).
I hope you like it!

P.S. Handpainted with a sliver sharpie (not a great look, but I like it). The two holes remaining are for the LED and a SPDT switch for LED diode clipping..
Hey Hector, nice work and congrats on getting it going! I'm diggin the sharpie action ;)
Where'dya get that enclosure?
I got that from an electronics store.. Here in Greece is difficult to find Hammond-like enclosures :-[. This was the closest thing ::).. But now I'm thinking to make my own boxes like this: http://www.geofex.com/Article_Folders/steelstud/steelstud.htm (http://www.geofex.com/Article_Folders/steelstud/steelstud.htm) ;)
nice build, the Dist+ is a pretty cool circuit. my first build was a Dist+ kit from BYOC years ago.
If you want to decrease the treble a little bit, add a capacitor in the feedback loop of the opamp. that's C5 on the tonepad layout (you can also increase the value if you already have one there). i suggest a pretty small value like 50pF or so.
Hi Hector,
i recorded a video of my distortion plus a while back and put it up on youtube and funny enough i actually talk about the, over the top, treble. I found if you turn the treble way down on your amp, like, half of what you would usually have it set to, it's quite usable. Took me a while to work that out, as i thought that just how it was suposed to sound, hollow and trebly. Once the treble is balanced it sounds pretty good imo!

Hope it helps, and good luck!

I've been eying Dist + ever since I found out it was responsible for some of my favorite sounds (probably on guitar at 0:20 on right channel http://www.youtube.com/watch?v=hvZseXEqdss&ob=av3n )
Neat enclosure, it looks geeky or military like. I swear my next box (or two) will be a Lego one once I get back into building ;)

Thanks! The Distroyer was my first build too. That started my addiction with DIY pedals, although I was dissapointed with it in the beginning.
I already have a 10 pF (I think..) like the schematic. I will try that and other values, until I take the sound I want. So, thank you for that!

Thanks, Paul! It was really helpful to hear another DIY Dist +, so I can compare it with mine. I can say that they sound almost the same!
I tried the same thing you say with my amp and tone control pot on my strat and I have better results. But that "destroys" my clean sound. So it's not so practical. I want a more permanent solution!
Hi Hector,
The only thing i could think of, in a live situation would be to use an EQ pedal. Or maybe as a future build you could build one? Also, look around for a mod for the dist+ to add a tone control to the circuit (might be too late for that though). I'm sure i've seen the discussion come up in the past. DIYSB forum has the dist+ as a beginner project. This would be the best place to look / ask about a tone control.
Hope it helps!
Paul
