I picked up a 1590xx to try stuff with and ended up using it as a dual pedal build with an Aion Blueshift and a PPCB Electrovibe Mini. I was originally thinking of a standalone mini board but a looper enclosure might be better for that. Here are a couple pics

I like using the Lumberg style jacks because they fit much easier in the builds I tend to do, and they space the DC plug further out so that it fits better with the patch cables I like to use. I try to buy genuine Lumberg if they aren't too expensive at whatever website I'm on at the time

If you are getting no signal at all with the pedal on then the simplest problem would be a short to ground in the signal path. I would use the continuity function on your meter and check that none of the signal along the audio path is shorted to ground. The signal passes thru R6 & R7, as well as...

Quite a while ago I was looking around on Aion FX to see if there was anything I'd like, and I found the Blueshift, which is a Boss Dimension C. I'd never done a dual layer board but I was hot off a successful Low Tide build and ready to take on the world! I wanted to make it with top jacks and...

Hi all, I finally had some good weather to clear coat some projects I started over the winter. Here is my build of a PCB 037. This board has the option to use either silicon diodes or LEDs for the clipping section so I wanted to utilize both via a switch. Here is the board built sans the...

Hi all, I see that I can get 1uf caps in MLCC and film variety - is there a reason to use an electrolytic cap instead? Rather, if the PCB calls for an electrolytic cap, can I substitute a film or MLCC of the same value without issue? I don't buy in to the mojo part theory that much. I'm sure...

Do you guys use these things? I'm married to them at work but I've never used them when building pedals. Most of my builds come out okay...

What I did was purchase a 16GB flash drive, download Windows 10 from the Microsoft website (found it googling windows for mac/boot camp download etc etc), which was free somehow, and set up Bootcamp as a partition on my hard drive so I can run Diptrace natively. Ever since I upgraded to...

^ Thank you. I breadboarded the Fuzz Aldrin last night and that's what I discovered, the caps going to ground affect the highs. and mid highs. I tried a few different value caps but my favorite sound was with the Brite control and C13 and 14 removed entirely, and the Q's swapped for BC108's. In...

^ does the decoupling cap need to be electrolytic?

Hi all, I'm learning more about circuit design. I noticed the Enchanted Boost doesn't use an electrolytic decoupling input cap, rather a standard film type. Is the electrolytic not necessary? I thought it was prudent to filter DC before the transistor. Thanks

Hi all, I built a Sandspur, which I love for its warm yet bright, saturated tone. Many pedals sound dark to me, especially with reverb, but this is great. I also built a Fuzz Aldrin and this suffers from the same kind of dark tone many overdrives do, unless I max the brite control and both the...

From what I've read on the LM386, it's an audio amplifier meant to drive a speaker, and in this case it's driving a PT2399. Various other analog delays use a TL072 to drive a PT2399, so why is this one different?

why not?

Hi all, I'm combing over the schem for the Chalumeau and I'm wondering why the design doesn't use a TL071 rather than the LM386? All the other delay designs use a regular op amp before the delay chip, what is different about this one? I intend to lift pins 1 and 8 and set the internal gain of...
