Use your meter on continuity mode to trace the path from the 9v + pad through the components of the LED path, to the switch, and to ground. Somewhere along the way there's a break. Find it and repair it

You might consider the Photon Vibe instead. Compared to the Electro Vibe, it has more throb and a treble and bass control while using the same incandescent light bulb LFO driver. The original circuit is nice, but thinner sounding than the Photon Vibe

I built a duocast and felt the same thing - it was okay but not my thing. I used a GT402 for the Ge transistor. It sold pretty quickly on reverb though

The build doc mentions what type of LED to use for LED4

The back of your tone pot is contacting the circuit board and should be insulated with one of those plastic dust caps - electrical tape isn't enough Lots of messy soldering but it looks like it should function - just pull up the tone pot away from the board and test again

My current favorite is the Mad Professor Amber Overdrive, available here as the Resinite OD. Oddly, it's a big muff circuit but sounds like a cranked Marshall Superlead. I wind back both the gain and volume to about 9 o'clock to get a warm and saturated tone with wonderful note definition and...

That will probably work better as I'm near the 300 pin limit on this project How do you mitigate mistakes without being able to run verification?

How do you make a project across two boards? Like the Byzantium Flanger for example. I have a feeling on how to do it: Make schem, then convert to layout. Experiment with layout and figure out the best place to separate the layout and set up headers. Then go back into schematic drawing, insert...

I'd like to see this as I'm considering decals for my labels but idfk what I'm doing

I'd love to see this too. The Amber OD is one of my favorite pedals and I'd love to see how others mod it. I keep both my gain and distortion at about 9 oclock, so different value pots and maybe something to give it more edge and less fuzz would be great. I like some of the fuzz saturation, but...

Hi all, I'm tracing a few schematics and noticed something about the TS schem that I can't figure out. In the schematics of the TS online, the RC filter (4k7 res & 47nf cap) in the first op amp is connected to ground (R4 and C3 here) But on the PPCB schem, they are connected to VREF. Same...

Thank you so much for writing that out. I'll check out electrosmash, and that freq analyzer site is awesome!

I'm trying to understand more about what gives certain pedals their freq response. For example, I really want to like my Distortr for the texture it has, but it always sounds either too shrill or too muffled. It doesn't speak with presence like my Luxury 763 or Amber OD, and I'd like to change...

You might also try cleaning this thing, as it goes from the LED that connects to pin 2 of the IC to somewhere

Verify whether you are getting something closer to VCC or VREF at pin 1 of the IC Reading thru your volt findings, if you compare pins 1-3 of the IC to pins 5-7, you can see there's a voltage diff between pins 3 and 2 and this is why the LED is constant on. Check to see if VREF is present at...
