Lets use this as an example

http://www.aronnelson.com/gallery/main.php/v/DRAGONFLY-LAYOUTS_0/album14/album143/DALLAS_RANGEMASTER_001.jpg.html

First off does the pot with the writing represent the top or bottom of the pot?

Second off I'm confused about which wires go to which sleeves on the jacks. I see two ways to read this, the first way is how the sleeves are physically layered distance wise. So if we say the end with the hole is the back would the sleeves be wired according to physically how far they are away from the hole? The other way I can see to read it is how the ends (the other side of the hole) are connected to the sleeves. So the small end would be connected to the one that is closest, the long end to the one that is in the middle and the one by it's self not connected to either.

Sorry if this isn't clear, but i think this is really messing me up on my pedals =\

When in doubt, follow the jack.

When you insert a plug, look for the part that touches the tip of the jack, then follow that back to the main body of the jack and look what layer it is. The other is the sleeve.

Or, if its stereo, the arm that doesn't touch the tip is the ring.

Oh ok ok yea, I get the tip, ring, and sleeve thing, what I don't get is by following that diagram which is which  :icon_redface:.

Also how the 2 jacks are connected, do they have to literally be connected togeather by a wire, or could you have a wire from each going into a board on the same from and then have another wire at the end of that going to the spot where they both connect, if that makes sense.

Hmmm.... that diagram is somewhat confusing, especially for a beginner.

From left to right it goes J1 (t, r, s) J2 (s, t)


for the second question, I'm not sure if I understand correctly, but as long as everything is electrically connected, it doesn't matter how it looks :)

It is easier for debugging to follow the layout as closely as possible, however.

Zach

Ok, I hadn't tried that wiring yet, so I'll give it a go.

Let me try to rephrase it. That green wire that is connected to both jacks, do they have to be directly connected, or does it matter if they are wired in such that they are indirectly connected on the board.

Thanks for your help =]

Zben3129

Yeah, you can connect a seperate wire from each to the board, in the same strip, as they will both be connected to each other and the place on the board.

Hmm so I can't get the bypass to work, no sound is coming out atall =[. I tried just connecting the jack to the jack  like jack---wire---jack, and no sound was coming out, is this because this won't work or wrong sleeves tips or rings being connected? =[

Zben3129

hmmm

well, if you just have the grounds (sleeves, shields) connected to each other, with no connection to the board, then with the effect on you will get nothing.

If you have a short between signal and ground somewhere, you will lose all your signal.


Check to make sure that you are using the switch right, some go agains logic with pin assignments. Check with a DMM for confirmation on what pressing closes and opens

Ok so I have the bypass working now, and some sound but I now have 2 problems.

1.) When the pot is turned all the way to the side it turns off my guitars signal to the amp, weather the pedal is on or off.

2.) When I turn the pot, it doesn't really seem to make a difference in the sound when on. I have tried an audio and linear pot.

BaLaClavaAa

Anyone have any idea of what I could do to fix these 2 problems?

BaLaClavaAa

Also does anyone have a link to an explination of how to add a dc socket aswell as a batery snap to a dpdt switch, can't seem to find one.

aron

The switch doesn't sound like it's wired correctly.

BaLaClavaAa

Oh ok i fixed everything. It sounds great  ;D. The only problem is that I can dial in the radio on it causing alot of background hum  ???, but I suppose that will be fixed when I put it in a case. Thanks for your help.

Zben3129

This will most likely be fixed if you put it in a shielding case, but I'm sure you know this.

If you put it in a metal case, you will be fine. Plastic, however, will not help with radio stations.

Zach

BaLaClavaAa

Yea, I have a couple of those cases from small bear. I can't believe building this actually worked  :icon_mrgreen:

Thanks for all your help Zben and Aron.

Zben3129

Congrats!

Its always nice when a build actually works  ;D
