Devistortion clone build in progress for Astricii.

Graphics done. Thought you guys might like to see.

Woah! Cool graphics!

Graphics are awesome! What 2 pedals make up the Devistortion?

Gorgeous looking pedal. What does the switch do???

That graphic is amazing!

how exactly did you do that graphic. I see a sharpie. tweet the deets

Thanks. I actually haven't decided yet. There are a few things I'm debating between. It was more my ocd need to have the drilling be symmetrical than a necessity.

I brought an image I found into Adobe Illustrator and cleaned up the lines. Then printed it out and using double sided tape affixed the print to some card stock. Then I used an exacto to cut out all the black except for the finest lines (in the hair on top, the hair tie, and nose). I first put down a few layers of white on the face of the pedal. Then I painted over it in black with the stencil I created. After that I drew in by hand the lines of the hair, hair tie, and nose. Then I put down a few layers of clear coat.

thats not sharpied on is it? some of the lines look to thin and precise to be sharpie, the lips make it look to me like it was airbrushed on, how did u do the graphics?

See above.

What's really upsetting me is an imperfection at the edge of the very top of the face. It started to rain while I was painting outside and caused some rippling before I could get it inside. It isn't very noticeable, but I may have to sand it out and try to fix it.

I had to sand out the first layer of white I put down when mere seconds after beginning to paint not 1 but 2 flies landed in the paint.

Tank Grrrrrl FTW!

Just finished the KP circuit. The circuit itself is 5/8" X 1/4" I left a little extra room around it with the board just because there isn't really a reason it needs to be smaller.

Looks like an Electra with low-pass filter on the input?

bubstance told me this in another thread:

if you remove the 2.2M in parallel with the input cap, add a 680R resistor to ground off the emitter of the MPSA18 and add some clipping diodes to ground after the second cap you've got an Electra distortion (which I'm sure was the starting point). Better yet, swap the 3.3M resistor for a diode and you've basically got a Bazz Fuss.

And the EB circuit. Made to fit nicely like the other one. 7/8" X 1/4" plus a little room around the board.

NOTE: For some reason I drew this one as a bottom up view and the other as a top down view. I'll redraw this one when I get a chance so they're from the same perspective. It isn't very important so long as you know that in each picture the transistors are oriented E, B, C (from top of image down).
