Wah Inductors. No hype. Just measurements.

Looks like a hot potz II, which puts it in the early 90s. Most likely a 1408P. Looks like a stock barrel connector to me...though it's possible that it's a modification.

That was a good era for crybaby inductors. Anything late 80s-mid 90s, really. In the late 80s they used a Magnetics type F 1811p. 90s...dunno the exact grade, but I know that they used an N30 1408p on some when they started making pedals for budda. I'd venture a guess that they used N48 for a while.

I see two possibilities: either it's an older 1811P variant from the late 1980s that was modified with a barrel plug instead of a 3.5mm input and a new pot, or it's a stock model from 1992 onwards. Can't remember if he used much wah on their self titled in 92, but I know it's all over evil empire.

His signature model is a GCB-95 with a paint job, unfortunately. Typically a stock toroid inductor: honestly, I'm not super impressed with dunlops toroids...but they're a fair sight better than the blue and black cans they used in the mid 80s.

I appreciate the thorough write up! You really know your stuff!

Remember, peak of mount stupid. To prove it: did you know that there was a crybaby that pre-dated the vox grey wah?

It just so happens that it's true! The vox grey wah was invented when the guitar player inventer, Roman Ed Paul, got tired of gently nudging his newborn with his foot to get that "wahhhh" sound. Plus, the kid was starting to sprout teeth and the penicillin injections after every gig were getting expensive. So he conjured the Vox Grey into existence by claiming that all other guitars aside from his were crap.

Deep cuts right there. I've been online for too much of my life.

Honestly, I'm looking through old photos. I wouldn't be surprised if he had multiple crybabies over the years. Could be he started out with one from the 80s, and went through a few.

Might have been cheaper to just keep knocking up another kid... endless supply of "wahhhh" — then again, the patrimony suits and lawyer fees for custody battles (letting the other side win once the kid is past its wahhhh-prime)...

Necessity is the mother of destruction. A penny saved is a penny kept out of the poor's grubby hands.

...DAMMIT, STICKMAN, STOP DERAILING YOUR OWN THREAD!

Wonder if any of these Dales would have some promise.

Took a quick look:

That's a negative. Nothing in the right range of 500-650mh. DCR values too high in the hundreds of millihenries.

Truthfully: If one wants to go on the cheaper side of things...I really like the Stompbox parts ME-6. Its a fantastic wah inductor for...like...stupid cheap.

I'd throw one of those in a pedal over a modern Red Fasel any day of the week.

A'ite folks, I've conquered the el rad.

No destruction this time around. In truth, it kinda looks like a lower value red fasel. Sorta. Higher DCR though.

Honestly, I've found the toroids that I've measured to vary the most. Could be minor variations in the ways that the wire is wrapped...being non-delicious donuts, rather than simple spools, it's a much more difficult prospect in trying to wind them consistently.

There are designs online for toroid winding machines, but they are generally designed to wind toroids in the 75-150mm diameter range. Too big. making a loop that would work for something this size would be difficult.

Colorsound documented too.

I'm also doing some revisions to my excel document. I'm now going to be taking every single measurement I can grab from my little LCR meter so I can have a more complete dataset moving forward.

Eventually I want to get all this stuff set up in such a way that one can select different attributes and generate comparative graphs and such. Cause that would be fun.

I gotta print that shit out. Trying to read it on my phone makes me go cross-eyed.
