Found some inductors. Any good for a wah pedal?

Hey, guys. The other day, I pulled some circuit boards from an old non working Kimball organ. There are four inductors and I'm curious as to whether they're useable in a wah pedal. They kinda resemble what I've seen in pictures of some vintage pedals. Thanks.

They have numbers on them, too. Two of them say ".35H" , one of them says ".80H" and the fourth one says "1.8H". I haven't pulled them from the boards yet, so I've no idea about their resistance.

Resistance isn't the issue.  They are marked with their inductance, so look at circuits you might want to use them in and compare.

Well, I was thinking about trying one in my Vox V847 wah pedal. I've been wanting to finish upgrading it to more of a classic sound. It's still running the stock MPSA18 transistors and the original pot. The only upgrade I don't want to do is true bypass. Thanks.

I finally tried all four of those inductors in my wah pedal and the 1.8H was the one that sounded best. It has a very strong, vocal like quality and sounds almost like Hendrix!

Here's the circuit board with the "new" inductor. I had to tweak the value of that cap between the inductor and Q2's emitter, but on the third attempt I found the sweet spot with a .0082uf cap. The tone and sweep of the pedal with these mods is just awesome. <3)
I've never enjoyed using any wah this much!  :dbtu:

Thanks, Juan. And a big thanks to the others who offered advice to point me in the right direction!  :tu:
