Hello. I recently completed my tearjerker wah and the pedal does the "wah" but the pot has no effect on the filter freq. The dip switches change the frequency and the trim pots do everything they should. I triplew checked that everything was wired right, reflowed, etc.. The pot is functional...

The red fasel inductor is 500mh right? I cannot find the specs anywhere

I would like to check out all the vref points on my pcb, but I don't know that the voltages are supposed to be. Thoughts on where I can find them?

https://photos.app.goo.gl/ptCC7qeCia1XuNtc6 Hello. I recently finished the photon vibe. I have a suspicion that my voltage regulator burned out. IN the early power part of the circuit I get no more than 15 volts instead of the 18 it is supposed to be. I cleaned my board with isopropyl and double...

I checked ground connections and soldering. Nothing appears to be shorting. Only thing that comes to mind is that I have an electrolytic cap that's rated for 10v but it doesn't get hot or anything. Any other ideas as to where this noise comes from? It overpowers the guitar signal quite a bit...

Hello! I am having a hard time finding the opa2134 ic on my vendor's site. Any alternatives?

Hello. Is the max1044 in the photon vibe interchangeable with small bear's tc1044scpa?

Hello! When looking for the max 1044, I came cross the suffixes esa,csa,cpa. What difference do these suffixes make? I ask because I remember reading that there was an important difference between cpa and scpa in charge pumps. Thanks in advance!

Hello. I was wondering if I could use 1/4 w watt resistors in place of the 1/8w resistors the build document calls for?

I checked the whole pcb and everything is where it should be. The lfo circuit works when I flash a flashlight at it, but it seems the led inside cannot produce enough light to make the pitch change enough. With the led inside alone, I only hear minor chorusing, but in demos the depth seems to be...

Hello. My sub oscillator tracks perfectly and plays the interval it was meant to make. However, the oscillator barely tracks and does not play the interval it is supposed to unless it is in vibrato mode. When the rotary know is turned for this oscillator there is this weird bit crushed sound...

Hello! The led in the circuit (5mm yellow) does not seem to put out enough light to make changes in pitch. I know that the modulation circuit works because light from my phone was capable of changing the pitch of the signal. Has anyone else encountered this problem with their pitch witch?

Hello! This project calls for an L78L05 ic. I was wondering if I could replace it with a L78L05CZ and other such varitaions with no problems. Do the letters that differ between these variations drastically affect the ics performance in this project? I can't find a place that sells an L78L05...
