I Am In Love....

I just occured to me while I was looking at old wah pedals on ebay which use odd looking inductors (which look more like an audio transformer) that maybe one could use half of an audio transformer as an inductor. I don't know which transformers exactly might work, but I would guess that Mouser has a couple of candidates in there somewhere. http://www.mouser.com/ds/2/449/XC-600134-205894.pdf

I've seen what looks like an audio transformer used in a vintage wah, but don't remember which one. R.G. Keen talks about using audio transformers in his "Technology of...." article. If you've got a dead radio around, there might be a transformer in there you could use to experiment.

I've seen those inductors in all kinds of off-brand wah and wah/fuzz pedals made overseas.

In some discussions here long long ago i the mists of time (or rather, The Time of Myst  :icon_lol: ), one of the points that Commander Keen noted about the "magic" inductors, was that the ferrite housing would acquire some magnetizing after a while, and that the production of various harmonics, in his estimation, was a byproduct of that effect of those materials.  hence the preference for Fasel inductors over other types with the exact same inductance reading.

Now, while the little transformers-as-inductors may meet the component-value requirements for producing a textbook wah sweep, consensus is that they will not really "do it" as far as inspiring wah sounds go.

But unanswered is the question of whether "yoy" benefits from ferrite housings in the same way that wah does.

So did you finish winding those inductors Mark?

Mark Hammer

Not yet.  Too many projects, plus I got/constructed a new guitar that is amusing me.  I have to finish constructing a new winding jig.  I bought a fishing reel that I think will do nicely for winding both inductors and pickups; I get about 5 turns and a bit per handle crank, and the gear mechanism is smoother than my hand drill.
