I just probed pin 1 and 28. No sound on either. Pin 28 is silent, pin 1 pops the amp frequently. Thanks for your help, Walter

Sorry, I misunderstood what you meant. I get dry sound on one end of the mix pot, the other end doesn't give any sound at all. Correct me if i'm wrong but i'm pretty sure it's the potentiometers having the wrong resistance. Thanks, Walter

Wanted to update this thread. I checked both ends of the mix port but it doesn't have any effect on the volume. I ended up replacing the switch but that didn't fix the problem either. I did realize that the potentiometers I used have the wrong resistance value (10k instead of 100k). I'll try...

I was able to fix the LED, it was burnt out. However, i'm only getting bypass sound when I try to use the pedal. Any specific points that I should look at? I've had this issue before but I don't know what I did to fix it. Thanks for your help, Walter

Hey everyone, I have assembled an Arachnid V2 guitar pedal but the LED isn't lighting up. This is because the LED is receiving the supply voltage (8-9 volts) instead of the rated 3.3v. I'm unsure of why this is happening, I haven't found any shorts and everything looks like it's correctly...

Does anyone know what could be going on? Should I provide more pictures?

Hello, I just soldered an Arachnid V2 guitar pedal and the effects work great. However, there is a slight ringing sound when I turn the pedal on. I can also hear several pops when turning the pedal on or off. Does anyone know what could be causing this? Thanks, Walter

It has been a while, here is an update. I got the pedal to work. I don't know what did it though. I just plugged it in one day and it started working. So I put it into the enclosure and now I am essentially back to square one. The sound works, but no effect. What is different from my original...

Both bottom potentiometers read 4.28 volts despite what setting they are at.

I tried the pedal couple more times and here is what I discovered. When the pedal is off the guitar sounds fine. When the pedal is turned on only the effect of the pedal is being amplified(you cannot hear the guitar). I ran the exact same settings on the working pedal and with the pedal on the...

I purchased the FV-1 pre-soldered. TL074CN Pins 1, 2 ,3,5,6,7,8,9,10,12,13,14 all read around 4.2 volts. Pin 4 reads around 8.5 while pin 11 doesn't have any voltage. FV-1(I tried my best with these measurements, if there are any critical pins that I should probe let me know) pins...

I checked all my solder connections and they all seem good. I reflowed the solder on the ground pin for the eeprom chip. Unfortunately this didn't solve the issues I have been having. Does anything else seem wrong about the solder connections and off board wiring? Let me know if I should...

Hi, I am trying to assemble an Arachnid V2 pedal but am encountering some difficulties. When I plug the pedal into the amp and guitar the bypass sound works and the LED on the pedal lights up but no effect is created.(I did try reversing the amp and guitar cables connected to the pedal) This is...
