Here's my humble offering. It's a slightly modified ROG Omega Boost in a small sloped front enclosure that's been in my junk box for 15-20 years. This is also my first try at DragonFly's acrylic swirl painting method. Not great, but not bad. 3mm LED is epoxied into a 1/8" hole.
Mods:
-Reduced output cap to 1uF (film). This still gave me decent levels down to 50Hz and usable bass to 40Hz.
-Added "Grit" switch to select three different bias points. 0 is 4.5V, 1 is about 5.5V, and 2 is about 6.5V.
One problem I have is that changing the master control puts a DC offset on the output. That was my motivation for reducing the output cap. If you turn it slowly it never builds up anything significant, but if you quickly turn it a few volts of offset appears on the offset and takes a few seconds to settle out (dang that 1M resistor). Otherwise this is a nice pedal--adds a certain sheen even with the range all the way up. Me like.
I built it on plain perf board (no copper)--also a first for me. Guts are a bit sloppy. I fashioned a bracket for the PCB using galvanized sheet metal so I wouldn't have to drill another hole in the chassis. That's a piece of blue fish paper to insulate the bottom of the board from the switch contacts.
