Hey guys, first time posting here!
My Emerald Ring/3DPT Wiring Board kit won’t work and I have no idea why.
Here’s a video showing my work:
Any help is appreciated!June 6, 2019 at 9:46 am #6026CybercowModerator
You have the ground and signal wires revered on the Emerald Ring PCB. Notice the little, tiny “T” on the silkscreen where your blue and black wires connect. The blue wires need to be connected to the “T” pads and the black wires go to the other pad. Good luck!June 6, 2019 at 9:58 am #6027AnonymousInactive
Thank you very much for replying. The blue wires already seem to be connected to the “T” pads. What else could it be?
Thanks again!June 6, 2019 at 10:20 am #6028AnonymousInactive
EDIT: I have no signal whether or not the pedal is bypassed. The only thing I get is a faint buzz/weird sound when the pedal is activated. I do get a distorted signal when I solder the cable that’s supposed to be on sleeve on the biggest part.June 6, 2019 at 10:34 am #6029AnonymousInactive
See this picture:
Also the LED isn’t working at all.June 6, 2019 at 12:18 pm #6030
It looks like the input jack is wired incorrectly. I think I see the Tip and Sleeve wires reversed.
Also, the circuit will not power up unless a plug is inserted into the IN jack.June 6, 2019 at 12:28 pm #6031AnonymousInactive
Thank you for your help, I will try inversing those tomorrow! Just wondering: is the Emerald Ring supposed to sound distorted? I did manage to get a sound of it but it was really distorted as I mentionned earlier.
Thanks again!June 6, 2019 at 12:47 pm #6032
The Emerald Ring will sound best when used after a fuzz or another distortion type pedal. The more complex the signal, the more the octave effect will be noticed. Let us know if you solve your issue.June 6, 2019 at 4:54 pm #6034CybercowModerator
Thanks for jumping in Wilkie – I didn’t catch that. It’s a little difficult making out the connects in video as opposed to simple, good, clear photos.June 6, 2019 at 6:32 pm #6035
We often need more than one set of eyes. I just paused his video to look closer, but I couldn’t enlarge it.June 7, 2019 at 2:32 am #6036AnonymousInactive
I’ve soldered the ground wire back on the biggest shaft of the input jack just like I had done yesterday and it works perfectly! The reason I had undone that modification yesterday was because I thought the pedal wasn’t supposed to sound distorted.
The LED still doesn’t work though, what could it be? I’ve tried turning it the other way around but that doesn’t seem to be problem. I can take some detailled pictures of the build if needed.
Thank you very much!June 7, 2019 at 10:42 am #6039AnonymousInactive
Bad news everyone: I wanted to change the wiring to something proprer and now I’m back to my starting point. No singal when the pedal is activated, what could it be?
Thank you very much and sorry for being such a noob.
Here is the current wiring:June 7, 2019 at 12:15 pm #6041BarryKeymaster
If there is no signal it is a wiring issue most likely but we cannot see the connections you have made to the Input side of the wiring board to Main Board with that photo. Revisit all of your wiring connections. Make sure you have solid connections everywhere. The one ground connected to the wiring board does not look very secure.June 7, 2019 at 12:19 pm #6042AnonymousInactive
Here a few other pictures I’ve taken:
Hope it helps!June 7, 2019 at 12:24 pm #6045BarryKeymaster
Black ground wires appear to be connected to the side of Tip Jack?
It should be like this:June 7, 2019 at 12:36 pm #6047AnonymousInactive
Thank you for your answer. The reason I did that is because I couldn’t make the pedal work by soldering the ground wires to the sleeve. The reason why the pedal is not working anymore is because I wanted to tidy up the whole thing and had to unsolder a few wires. I must have messed something up while resoldering those.
P.S. – I short circuited the battery prior to having the current wiring of the pedal, could it have affected some of the components?
Thanks!June 7, 2019 at 12:44 pm #6048
The wiring connections on the IN jack are incorrect. You do not solder wires directly to the large contacts. Take your guitar cable plug and insert it into the jack. You will see that the tip of the guitar plug will make contact with the longest curved contact. Now look closely at that long contact and you will see that a part of it is a solder lug on the opposite side of the jack. That is the lug you need to solder the yellow wire that goes to the “IN” on the 3PDT board. Now look at the shorter curved contact. On the opposite side of the jack is the solder lug for this contact. That is the “RING” contact. It makes a connection to the middle “ring” on the guitar plug. You need to solder the black wire going to the battery clip to this lug. The shaft of the guitar plug is making contact with the shell of the jack. In the middle of the jack is a lug that is attached to the shell of the jack. This is the “Sleeve” lug. Solder the black wire that goes to a ground pad on the 3PDT board.
Once you get the wiring corrected, you may also have fixed the LED issue. If not try reversing the LED again. (I am happy to see you used a socket for that!)
