I did use 100nf caps, yes.
nah, I mean, did you use any special flavors of 100nF?
No sir, just whatever Tayda sells.

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.


Got my Dragonthayur board working! Like I said, many mistakes in my design that I'm rectifying, but overall, I love the sound. One weird thing: I've seen other schematics (and the Lizard Queen) call out different component values for the transistors, and particularly Q1: I was getting almost no signal out until I changed Q1 for a Darlington (MPSA13 per Brian's schematic). Started out with a 2n2222, and it reads good before and after, had solid joints too, so no idea what was going on. But it works now!

revised layout (so far) in a 1590B with 19mm Davies knobs and non-sub-miniature SPDT

and with 13mm Davies knobs

new board is still spaghetti and looks awful, so no shots of that yet

1590B will have side jacks. My working model is a 1590N1/125B, so it gets top jacks. That thing, though, is uglier than my board (really bad PLA print AND bondo...yikes)

Nice work on this one, Brian, sounds great and the white LED lends a nice tonal variation. Now to finish up the hand-etch board build.
