Yea I preferred exhibit 2, interesting about the high inductance. I'm interested in building my first wah, are there any magic numbers or rules with the inductor to make it work and sound ok? I'm on a student budget and want it to be simple as possible
Many threads on this board about wah inductors.
One example of that aspect in particular: http://www.diystompboxes.com/smfforum/index.php?topic=85590.0
I've tried most of the inductors I have, including one monster from a car stereo amp (filter inductor). With the right components, a wah is possible from just about any inductor, within reason. I have a couple 5lbs. monster (110AC in, 2x110AC @(4A?) each, or 2A each for a total of 4. I could probably get them to filter, but I wouldn't want to tote it around... probably require a monster amount of current driving it, too.
That's one thing I noticed... I tried the big filter inductor again a couple weeks ago. I did it first with a darlingtons, first tranny with a 4.7k C/120R E setup, biased to 4.5V, and it worked ok... kinda dark, like I remembered from before. Then I got the bright idea of using a 386. I tinkered and got it working. The current from the 386 definitely made a difference, at least that's what I'm guessing. The first time I tried it was in the nnormal Crybaby values, tweaked to make it work. I think it was even darker sounding then.
