A Very Cool Team Effort Dimetrodon Distortion...

Okay - short version of the build report here, but I did want to show off the way cool enclosure.

For my single tone stack Dimetrodons, I'm still using the board my good friend at South Obolon FX laid out for me. This has been a really solid little board, and I've nearly gone through my whole first order of 25 of them (and as a matter of fact I just ordered some more!). I wanted to do something fun and a little different for this pedal, so I decided to go with carbon film resistors and the red epoxy film capacitors to give it a bit of an "old school" look inside. I also went with the Triangle BMP tone stack - which I haven't tried before, but should be very close to the Sovtek stack based on the tone stack calculations I've done previously. The rest of the parts are my normal load out of diodes as well as tantalum and electrolytic capacitors. The IC (not yet installed above) and transistor are all new production.

Since this pedal has a battery option (which means the back may actually occasionally get opened), I went ahead and added the trimmer to adjust the LED brightness on the 3PDT daughter board. If I can get enough of the trimmers in bulk, I may start doing this on more of my pedals as it is a kind of nice option for people who play both indoors and outdoors. I'm using ribbon cable to connect the main PCB to the daughter board - although because of how the PCB is set up I do have to do some surgery on it. It's still quicker and easier than cutting and stripping individual lengths of wire! The jacks are all connected with aviation grade wire from Tube Depot and insulated with heat shrink tubing.

For the enclosure this time around I went a different route. While the enclosure was drilled by Tayda, it was powder coated and silkscreened by Chicken Wing Audio ( @steviejr92 ) - and it came out amazing! As to the art, the dimetrodon is part of a larger block print by linocut artist Brian Reedy who kindly allowed the studio to license his work. I added the rest of the graphics and included Brian's logo as well. The simple black with the copper colored enclosure really seems to pop.

The pedal sounds absolutely great, and it does have the slightly greater bass character as you approach the midpoint on the tone knob as expected based on the triangle tone stack.

Stealin' the LED trimmer idea! There's pedals I got here that got tape over the LEDs. Friggin' floodlights.

That tongue-breaking name there made the word Distordion pop up in my mind. Works for a wavefolder pedal...
