Need some help with Great Destroyer build
Hello, once again i've become confused whilst trying to work out how to wire/build a pedal. I want to build the great destroyer on a vero board, found here:
http://tagboardeffects.blogspot.co.uk/2 ... royer.html
The circuit looks fairly straight forward, what i'm struggling with is how to wire this to footswitch, jacks, pots etc.
I've had a go at drawing a diagram but there are some things i'm not sure about, hopefully somebody could point me in the right direction.
This is what i came up with: (bare in mind i'm a complete novice so this could be entirely wrong; i'm also aware that the diagram resembles the scribbling of a lonely child, for that i apologise)
http://s14.postimage.org/lt54f80pd/Grea ... _build.jpg
My questions are, where is the 'ground' coming off the circuit wired to? Where is the 'ground' coming off the volume pot wired to? And i know there is some wiring missing from the input and output jack and also the DC jack but i can't for the life of me work it out.
Any help would be greatly appreciated
Much love

I noticed you have no LED resistor, and no V+ power to the footswitch for the LED. thats all you need there but I don't like doing it that way. your footswitch should already have ground for the grounded effect input while in bypass. you can use the footswitch ground to turn the LED on since the LED will only be ON when the input of the effect is not grounded.
this is my version for grounded input and grounded output. keeps any loud pedal quiet when bypassed.

to answer your question about ground. ground is ground. everything labeled ground is connected. it may not be a direct connection but if you follow the wires you will see that all grounds are connected through something that connects to something else. its all the same. there are some techniques to make your audio grounds a little cleaner than your power grounds but you don't need to worry about all that stuff.
P.S. you might have noticed my power ground does not run to the board or the other jack. this is a little trick where I use the metal box like a wire. it does not work on painted boxes, plastic jacks etc..

Please let it be known that we do not appreciate our designs be stolen and cloned. We sell a kit for fucks sake. I would also note that the schematic itself is incorrect.
I am really disappointed that this kind of shit is considered totally fine around here. This is how we pay our bills and you are flat out stealing it. Fuck off, please.

Yeah, I always do grounded input AND output when bypassed too. It's a good practice, and I'm surprised more builders don't do it; the extra lug is there for it. High gain distortions and fuzzes can sometimes whine when in bypass if all controls are pegged, unless you have the output grounded.

My question was only really about wiring pots, jacks etc, i'm just trying to learn how to do it, it wasn't really specific to this pedal. I found the vero circuit on that website so assumed someone had asked for permission to put it up. Not trying to steal designs, just trying to learn how to build...would prove pretty difficult if i wasn't allowed to build a pedal that already exists.

maybe now people will believe me when I say that it is NOT OK to reverse engineer or post schematics of anything from small pedal makers without permission. myself included this is how we eat. these things exist because we spend %100 of our time designing it and building it. eatyourguitar means I actually eat from selling my guitar if I need to. that hasn't happened yet but think before you clone. at the very least don't destroy a good forum by scarring off all the builders and ruining the #1 source of donations (the pedal makers!) that keep this web page in front of your face.

you didn't know so no harm there. but now you know so that should be the last time posting stuff thats ILF related without permission.

I completely agree, won't happen again. Like i said before this is just more of a learning process.

Re: Need some help with Great Destroyer build
While educating Paddy on the BS of a website publishing a (albeit wrong) schematic to facilitate cloning is important, the "fuck off" sentiment would be more appropriately directed at the publishers of the content. I would even dare to argue that the DIY cloners' postings are actually positive marketing. The websites publishing cloning instructions, on the other hand, are hurting the very sub-culture they love - all in my opinion of course. It's a tricky industry because electronic circuits of this nature are not considered to be novel and are, therefore, not protected by patent law.

Re: Need some help with Great Destroyer build
I think dear wife and I both got pretty hot when we came upon the thread. (we were sitting next to eachother)
Kevin, yeah, the "fuck off" would be better directed at the schematic publisher. I'll take half the heat for that post, it was a team effort.
Building pedals is a good kind of knowledge to have, especially when your shit breaks! Obviously we prefer to spread that information via our DIY kits (and my dear wife's endless email support)
I understand how one would assume it was all cool to build these on their own, and to be honest, there's next to nothing we can do about home made clones. I'm really glad to see that we haven't ruffled too many feathers trying to keep a handle on our little piece of the pie. We do sympathize very much with The Quest For New Sound And Information, which is why we offer our kit. That way both parties benefit.
Paddy, as far as a general education, the DIY section here is a GREAT resource for learning the mechanics of pedals, so you're in the right place.
PEACE.

It's okay to change your mind, but you don't have to tell us to fuck off and accuse us of being thieves in the process.
YOU gave us permission.

That is so funny cause I swore when I was reading this thread I have seen Aen post somewhere about this topic before and he was pretty cool about the whole situation.
Either way I have learned SO MUCH just by creating clones and modding them and most of them never made it to the boxing stage. It fuels the fire to want to build my own "original" effects and helps you learn on the way.
Forums like this and Madbean and other big name forums are perfect for the up and coming builder. I have yet to meet a boutique builder that didn't make a clone once.. I feel its part of the process of becoming a builder.

yup it is grey area. all I can say about it is try to find the middle path and don't piss off too many people on your way to the top cause those are the same people that can make or break you. this holds true for builders, retailers, guitar players, website administrators, famous people. basically anyone with a mouth and/or an internet.
FSB is a place where people just don't give a fuck what anyone thinks. it is totally punk and totally indestructible. think of it like a video game. if you choose the dark side you make enemies with the very people who would otherwise be your friends and help you. choose the middle path. no one knows what your reading if you don't make a post about it. gain the knowledge, keep the friends.

Re: Need some help with Great Destroyer build
That's certainly an example of me trying to make peace over there. FSB started tearing me apart from moment one, and there I took the high road. I can't see the thread, as I've long since forgotten my login info (I only registered there to defend myself) but I can see plenty of bravado in that direct quote you posted.
Well, bravado only gets you so far. This afternoon and evening's responses come from a much more honest and vulnerable place.
Offering kits was our solution to best serve all parties.
