That makes sense. I was thinking of it like a dying 9V battery lowering the headroom on a pedal but if the 9V measurement is from the drain to ground then what you are saying makes more sense.

This is my third PedalPCB build and the first where I didn't have to come to the forums for help. I just plugged it in and it worked! I love the sound of it, it is definitely going to replace the Son of Ben on my pedalboard as my low wattage amp-in-a-box pedal. I think I may swap the knobs for...

Problem: While trying to bias trim pot 1 on a Son of Ben PCB, the desired resistance was not within the trim pot range even with the trim pot at either extreme. Solution: The jumper between the drain of Q1 and the cathode of D100 was not properly attached. I removed the pcb from the case and...

Thank you both! That is very helpful. I will update the OP and mark this thread as Solved.

I tested the continuity with a multimeter. I got a beep between lugs 2A and 2B and between 3B and the remaining (left) solder pad. Does this help narrow down which holes to bridge?

Thank you! I thought the solder bridge must be mimicking the dual gang in this way. I don't know which of the two options it is but this narrows down the potential solutions. Good spot on the melted capacitor, I will definitely replace it before trying to do anything with the pots.

Here's the spot on the schematic showing the Bass potentiometer that I think the solder bridge effects. I don't see anything on here indicating where that solder bridge is located in the circuit but I am a novice at this. I was able to find some dual gang B1M pots so if I am unable to fix it for...

Thanks, that's good to know. Is there a way to tell what the pad was connected to? I don't see any tracers going to that area.

I'm not sure what the purpose of the bridge is, the pads don't look like they are connected to the unused holes.

Problem: A solder pad on the Son of Ben PCB came off while installing components. The PCB requires a conducting bridge between the two solder pads when using a single gang potentiometer in the bass pot position. Solution: Bridge the two component holes as shown in the picture below by soldering...

Thank you everyone for your help. It means a lot to know that you're not banging your head against the wall by yourself! I ended up taking out the parts and replacing components to see if I could find the issue and it looks like the culprit was a bad footswitch (I probably cooked it while...

Here's a picture of the otherside of the pcb before I soldered in the jacks and switches

I tried swapping the wires but still no sound and now I don't get a signal through the pedal when it is not plugged in like I was getting before.

Are they both wrong? I have had a very hard time trying to look up which lead is supposed to go to which part of the pcb.

Thank you for your response. The build instructions call for two two 10K ohm resistors at the spots I've circled below. I measured both resistors I put there and compared them to my other resistors and they both seem to be 10K ohms.

I've done some more testing. I seem to get a voltage reading when testing with a multimeter from the power input to other components on the board. Also I can get a bypass signal when the pedal is unplugged from the power, but nothing when the 9v is plugged in.

As it says in the title, when I connect my pedal to power I can turn on the right LED but I don't get any sound, bypass or otherwise. The left LED won't turn on at all. This is my first pedal build so any advice on what might be wrong or how to troubleshoot would be appreciated.

Thank you for the quick response, I will take a look at switch those caps as well. Do you know if the right side comes first in the circuit? I think that is how the King of Tone works (it will be a few years before my name comes up on the waitlist to test it out in person).

I am building a Paragon Mini and I am starting to solder in the components. The paragon mini is a dual pedal with two sides that can work independently. You can convert the pedal to a high gain option by swapping a 1K resistor for a 100K resistor at a specific point in the circuit. I'd like to...
