Fulltone Clyde Deluxe Reverse Engineer

[Jdansti]

CORRECTIONS

The resistor in parallel with the led is a 4.7k    not 470ohm
The resistor on the far left of the control board is a 1M   not 100k

And the trimmer on the main board is a 2k    not 22k



@ John     these don't apply to the boards I sent you. I marked all of the correct values on yours.

Gracias, mi amigo!

IT WORKS!
I don't have the selector switch at the moment so I hardwired in a 15N cap.
I will have a wiring diagram posted up soon.

It's throaty with that good highend snap. I'm very pleased with the sound


I dub this pedal 'Clyde's Revenge'          a REVerse ENGineered Clyde Deluxe

Great job!

I took the liberty to draw up a schematic with my limited eagle skills.
Is it okay if I post it?

[haveyouseenhim]

How dare you want to post in my thread!    yea   go ahead.   I'm not so good with drawing up schematics.

Well, thanks for the permission but it was more like a ethical/copyright kind of thing. (I know there are some schematics that are not allowed to post, which I support btw.)

I have a question about a resistor I circled in red. I can't see it on your board.
Also I couldn't add values for the caps...probably because I chose the wrong cap symbol or something.
I labelled the wires W1-7. I'm thinking W1 is IN. W3 goes to ground (to daughter board or from pot maybe?), W5 goes passed a 10nF cap to a pad in the corner behind the inductor.

What inductor and pot did you use?


On to the subpar schematic (so far only the main board):

^ I couldn't even begin to tell you if that's right because of my inexperience 



I took some voltages on the wah I used to clone from. 


Q1       (the one closer to the inductor.)

E   97 mv
C  4.33v
B  .69v


Q2

E  3.29
C  9.15
B  3.74

that resistor is 33 k

Mike- Which inductor are you using and where did you get it?

I have 2 inductors. Both salvaged from guts of a vox v847 and a crybaby.     I'm going to have a switch that switches between them to see if there's any difference

Thank you for doing this. When I get some cash I'm going to build this. And it will be beautiful!
Would you mind sorting out where the wires go?
If you do that maybe I could draw up the daughter board as well.

Also, the circled resistor, is it soldered in parallel with the inductor?

[haveyouseenhim]

I'm drawing up a final layout and build guide right now. it may be tomorrow or Friday before I can post it.

[haveyouseenhim]

layout updated!  (see below)   

[Keeb]

That's just fantastic!

I created this in Eagle. As you can see my schematic drawing skills are limited.
I labelled the wires even if I connected them on the schematic. I'm not sure where W5 goes but that's a simple fix.
If anyone wants the eagle file, let me know.

[alexradium]

any Vox/crybaby schematic and pcb layout is the same as this Fulltone,the only variables being: pot in place of the usual 68k in input;
cap selector for the usual 10n sweep cap;variable emitter resistor on Q1.
these mods can be performed on any existing crybaby boards.
That said,the key for the specific Fulltone sound is the inductor/pot combination.

thanks for the schemmy!    I hate photobucket. I made changes to the layout and it will NOT update.    It's weird.   I uploaded the updated layout and posted it but it stays the same.

I said in my last post that w5 goes to ground       

[haveyouseenhim]

Ok    this should be the final layout. (unless there's more mistakes)

on the dpdt switch pin 5 goes to lug 3 of the pot....not to ground      and w5 goes to ground

Has anyone verified this?

Gran Aporte!!!!!!
Sin duda voy a empezar a trabajar en este pedal de inmediato.

Enhorabuena.

Pues comenta si te va bien, porque y lo he hecho y es un wah muy sutil, es posible que  algo haya hecho yo mal

Please let us know it yours work fine, because mine not. it's a very subtle wah, it's possible I made something wrong ,apologies for my english

[Keeb]

Sorry for necroposting like this but I feel like I owe it to Mike for his great work on this circuit (and also to honor my promise to build this!).

This layout works. I used 2SC1815 transistors and they work great. Also I used a smaller rotary switch. I realised after I had etched the daughter board that it wouldn't really fit in a crybaby shell without really precise drilling. Too close for comfort, so I wired the switch.
