So i know if you reverse the in/out on some wahs it makes the seagull effect, i was wondering if you could wire a toggle switch to reverse the in/out of it ?

I don't know about one switch changing two channels, but you could definitely use 2 toggle switches, 1 to change each path.

I don't know, so long as it switches two things at once, then it should work.
I've just been looking up a heap pics trying to find a decent wiring diagram that's labeled then i could just work it out.

There would definitely be a way. The 4 switch would probably work but it's getting late and i can't work it out tonight. Look through some wiring diagrams, you need to find one that will let you change 2 thigns at once, then that way will work.

you only need a dpdt. just google 'dpdt polarity reversing switch'. wiring it is the same no matter what you are reversing, be it the in/out of a pedal, +/- of a battery, hot/gnd of a pickup, etc.

Would this work?

Say i have my wah on a pedalboard, i have it set as a wah, i flick the switch, and the current would still go through the rest of my pedals and into my amp, without having to unplug anything ?

hey, i just wired it up and it didnt work, nothing came through so i'm guessing i wired it wrong

12
34
56

i wired the + of the input to 1
- input to 2
+ output to 3
- output to 4
then jumped 1 to 6
and 2 to 5

could you tell me how im meant to ?

input jack tip to 3.
Output jack tip to 4
circuit input to 1 OR 5.
circuit output to 2 OR 6.
jumper 1 to 6.
jumper 2 to 5.

the way you had it, you were swapping around the hot and gnd of the jacks. the signal never even got to the pedal because it was grounded out in both positions.

Pretty dumb question, but im a bit of a newbie with modding pedals and such.
Where can i find the input/output of the circuit ?

There are 2 wires going for the input/output jacks. One is "hot" and the other is ground.
The ground wires are connected together and the hot wires are connected to the switch.



Mine's soldered onto the PCB
I wired the two tips to the switch how jim said, but im having trouble finding the 'input and output to the circuit' :/

the jacks are pc mount, yes? to find the input and output of the circuit, just trace where the tips of the jacks went when the bypass switch is in Effect mode..

this sounds interesting.
Just basically swap the input and output? Sounds easy enough.
I added an output buffer to my GCB-95 (otherwise the fuzz pedal following the wah, kinda kills the wah effect). guess I would also have to figure that into the design.

any examples of how this sounds?

Input buffer maybe. But mine didn't have an output buffer.
Maybe later version did.
It works with the fuzz now whereas before it didn't. It also added a little bit of boost.

95's only have an input buffer.

the 'seagull' effect sounds best with no buffers and idk if it even works with 2 buffers.

The middle section of Echoes by Pink Floyd.

I don't know how well this would work in conjunction with other effects, especially buffered ones. It probably wouldn't sound so great though.

I think it has to go at the very beginning of the chain as the tone knob is really acting as a component in the wah's circuit.

You can't simply solder the wires to the output and input jack solder pads and have this work. You are going to have to cut all the traces coming from the jacks tips and run wires to the outer sets of lugs on the switch also.

Ok. I did this really quick so someone may want to look over this before actually cutting. I personally would just remove the jacks and use chassis mount jacks. You probably wouldn't have to cut anything that way.

Basically you are going to need to isolate the jack tips so any trace coming off them (except for the ones that connect the two jack tips together) will need to be cut. Then all the points that were severed from the tip of that one jack that has all the traces off the tip solder pads need to be all connected together.

No problem.
Here's a how to from the Gilmore site:

- How do I make the “seagull” sound during the mid-section on Echoes?

This is a little complicated to describe, so let’s take this one step at a time… Note that this effect doesn’t work that well on humbuckers and it’s best achieved with either Vox or Dunlop Cry Baby wah wahs.

1. Connect your guitar to the OUTPUT and your amp/next effect to the INPUT on the Wah Wah,- reversed connection.
2. Set the pickup switch on your guitar in the 4. position (2. position from the bottom). Make sure that all 3 knobs are on 10.
3. Turn on the Wah Wah and let it stay with the “heel” all the way down. You should now hear a loud feedback.
4. Adjust the pitch of the feedback by carefully rolling down the lower tone knob (farthest from you). You should hear that the tone is pitched down. Somewhere between 2-3 the tone fades, but by making a really slow fadeout you can achieve the “laughing” effect.
5. Combine these techniques with switching the pickup switch up and down from position 1-5 and by adjusting the pitch on the wah wah.
- you’ll need to play quite loud and use some delay, 310ms.

Yeah, it's ****ed. I soldered all the trace parts back together now it doesnt 'wah' properly. Tried re-orienting the pot and allsorts :/

nah it's all back as it was. Where the traces were cut i've soldered wire between the components to bypass the traces. if that makes sense ? haha

Well I've looked over it a dozen times. As illustrated, it should absolutely work.

On the output jack, we just have to cut the one trace to isolate the jack tip.

On the input jack, we have to cut all the traces from both solder lugs of the jack tip. Then we have to connect them all together so signal will pass.

This leaves you with 4 connections on the board to be wired to the switch.

Not too complicated really. My guess is you didn't do it right especially since it doesn't work when you tried to reverse it.

Make sure you cut the right traces and didn't slip and cut any extra traces. Did you scrape enough of the green solder mask off each side of the cuts to solder properly? A multimeter with a continuity test can verify that you made proper connections. Did your cuts actually sever the trace? It only takes a hairline of copper to pass signal.

Can you post pictures? Maybe we can spot something. Also, did you try reversing the cables before doing this to make sure your wah will even make the sound?

Right, i dunno what happenned, but it's working again now :/
That was weird
i dunno what happenned tbh, i'll have another go tomorrow. Am i best off just using a craft knife to scrape the traces ?

did you try reversing the cables before doing this to make sure your wah will even make the sound?

yeah i did, works fine !
