I like the David Gilmour seagull effect but it is a pita to use a backwards wah or run the cables backwards so I want to make a dedicated box to do it with the jacks in the normal locations. There's a pedal called a Gullmour that's like this and some people on youtube have built them but nobody ever says how they made it and googling DIY ideas comes up blank.

I'm thinking: gut my Cry Baby, get a single coil pickup and a tone and volume pot (all of which I already have), buy an enclosure from Pedal Parts Plus to put all of it in, set and forget the wah pot and use the volume and tone pots manually to control the effect.

I'm sure my idea would work since it is basically just rehousing a wah and stripping a Strat down to a pickup and 2 pots but is an entire wah pcb necessary? I'm trying to think of the minimum amount of circuitry and parts possible to keep the size small.

Sometimes the easiest solution takes a while to present itself but it finally did. I got to thinking about what was the main issue here and it was either running cables reversed or having the wah with the front facing me. So why not reverse the wah jacks internally?

Before. Stock Dunlop Cry Baby GCB95 circuit board.



I removed the stock jacks, added standard mono jacks and reversed the input and output wiring. I forgot to run the battery cable under the pcb but zfg. Also, no battery power now but I never use batteries in my pedals so no loss.

After. New jacks and four wires. Easy and it worked the first time.



Video of the pedal in action. This is the first time I plugged it in. It worked and I rule.
