Howdy!

I think I've got the wiring correct on this pedal but before I plug it in and possibly blow something up I was wondering if ya'll wouldn't mind just giving it spot check? I'm mostly concerned about the stomp switch and DC jack wiring and the 1/4 input jacks. Everything else I'm pretty confident on.

Supposing SW on PCB is designated for LED cathode, everything is OK.. :icon_wink:
(except PCB OUT grounded when bypassed..)

P.S.
Both IN & OUT are grounded via Clean & Volume pot respectively, so you don't even need grounding for input..

Hi Antonis thanks for the reply! I posted the schematic and wiring diagram. I'm kind of new to pedal building so not everything you said I understood.

No the DC jack is wrong.  But it will work anyway since you're not using a battery.



Also, I'm not seeing how board ground connects to jack ground or enclosure.

Black wire goes to the central lug on the DC jack and the white wire is positive. They go through the 3PDT switch to the board at the bottom (4 pairs of wires, blue/white/yel/blk)

Here's a hopefully better photo of the completed wired pedal. I have to replace the switch, I must have broken it. So I have to re-do the switch wiring. But please, check out the in/out plugs and DC power to see if it looks good now.

LED and pots I'm confident on. But in/out plugs, switch and DC jack I'm concerned about. Thank you folks! This is my first pedal build.

it looks to me as tho you have connected the sleeve of both jacks to the footswitch, for to bypass them/it, and the jack tips are both hard wired to the board. this won't work as you think it might.

Hmmm. That's how the wiring diagram showed them to be wired. Should the sleeve be wired to ground and the tip to the switch? I'm confused :)

I'm less certain of this than I was when I typed it.  Best to move your + wire to the other lug either way.

Definately, yes.. :icon_wink:
(but, as far as it concerns to mono jack, I'm sure you've wired tip and not sleeve..)

But maybe Stephen, as a much younger guy, has more sharp eye.. :icon_wink:

well here's what I see. the white wire is connected to the tip lug of this jack, and disappears under the board. if connected directly to the board, it won't be switched by the bypass switch.



in this, the green wire is connected to the sleeve lug, and then to the footswitch where signal ought to be. the tip lug has been soldered, but if there is still a wire, it is invisible. the white wire is connected to the switched contact lug, which is of little use in this application, as when a plug is inserted, the switch goes open circuit. actually, without the jack in my hand, I think that bit is wrong - the switching finger would be opposite its lug, surely. so ignore those 2 arrows on the dia, but the green wire still wrong.


or - argue me something more conclusive, please.

I'm not sure about exactly which photo we're talking about..

So let's drink a beer - cider till OP decides for the particular wiring.. :icon_wink:

Howdy! Sorry for the delay. I'm waiting for a new order of 3PDT switches to arrive because I broke the one in the current wiring and I ordered some new Switchcraft jacks too. I'll post an updated wiring photo based on your feedback and some other learnings I've made. In the mean time, I built an AionFX Rift (Vox super fuzz) over the weekend and it sounds lovely. I just really want to get this Sun Face going to compare and see which I love best. I don't use a lot of fuzz but I'm finding some good "clean" fuzz tones that I like for simple lead licks.

Will reply back soon! Thank you for your support and patience!

Hello! I have re-wired the mono switches and the 3PDT. When I tried to fire it up -- nada. Nothing. Zilch. No LED, nothing. The signal passes through the box to the amp when I switch it on or off. I followed the wiring diagram from Pedal PCB to a T but I'm at a loss. https://www.pedalpcb.com/docs/Sunflower.pdf

Here is an updated photo of the wiring. I hope it helps.

Again, you need to move the white wire on your DC jack to the unused lug.  I can't see everything in your pics, but it looks like you have sleeve and tip reversed on your output jack, at least.  I think the footswitch is also wired incorrectly, but like I said, I can't see everything.

I'll check out the DC jack again. There are three lugs. The L-lug is the negative by my research and the two other lugs I was under the belief that it didn't matter which one you used.

The mono switches are giving me trouble b/c the wiring diagram shows a PCB mounted switch and I have regular switches. Also, the 3PDT is wired exactly as in the wiring diagram. So if you look at the wiring diagram you can see exactly how it's wired.

I made an error in my first post above, when I said it should still work.  Yes, the big L lug is negative (center pin).  But that middle one you used for positive gets disconnected when you insert a plug, normally that cuts off the battery.  So as it is, you're getting no power to your board.

Jacks, you mean.  But just look at them, what solder lug is connected to what contact, and what part of a mono plug that will touch when inserted.

Okay, you do seem to have that part correct.  I got confused by the twisted wires in the picture I was looking at, my bad.


Also, I assume you're putting an output cap in the sockets for listening tests...?
