Just stumbled across this on FSB. It's a tap tempo + modulation add on for PT2399 delays designed by Electric Canary. It is digital so you'll either need to buy a pre-programed chipset or burn the code onto the chips yourself. Lots of off board wiring with this, but it's probably worth if you have a favorite PT2399 delay you want to take to the next level. Check out their site for more info, schematic and the code.

Way Huge Red Llama 25th Anniversary Reissue
Happy New Year, everybody! This one recently got traced over on FSB. The 25th Anniversary edition of the Red Llama has an added hi cut tone control, but also has a few variations from the original circuit. The hi cut itself is just a basic cap/pot to ground tone control, the minimum gain resistor on the first stage has been reduced from 100k to 91k, and the 2nd stage feedback loop resistance has doubled up from 1M to 2M. Schematic and more info on FSB.

Dirt Master
Here's a little something I whipped up the other night on a whim. Actually built it on the fly before I even drew up a layout. I was trying to build something with some old mojo caps I found on my bench, and it initially started as a treble booster, but I ended up wanting more gain. Initially it was based on the EQD Arrows, but added an extra cap off the emitter (ala the Rangemaster) for more gain and snarl. I used a germanium transistor with an hFE of around 230. Worked well with a silicon transistor as well. Room for experimenting with the input and output caps. Should fit easily in a 1590B.

Mid-Fi Electronics Random Number Generator
Happy Fuzz Friday, all! Here's a fun noise maker that should go together pretty easily. Schematic for reference.

Grind Customs FX Tenebrion
The Tenebrion was designed by CultureJam and is the further development of the Box of Hall reverb. It uses the Belton BTDR-2 reverb brick, which I've designed to fit on the solder-side of the circuit board. You should be able to squeeze it into a 1590B.

EAGLE Tutorial
Finally gotten around to creating this tutorial! There's a lot, so it will be released in several videos over the next couple weeks, but the first two are live on YouTube now. So if you're interested in learning Eagle CAD to layout your own PCBs, either for etching, milling or fabrication, go check it out!
