Hi guys, so i figured i should post a new thread now that i got the buzz gone on my weener.....i have no wah effect whatsoever, it's just acting as a volume pedal???

The inductor could also be shot. I've had this happen before.

how would I test the inductor

rullywowr

Im honestly not sure. I would swap a known working one to see if it makes it go.

agree it could be the inductor too

A continuity check across the leads will show a broken coil, more precise measurement is a bit trickier

More likely you have a bad joint or trace somewhere inline with the inductor or transistor

i have continuity between two of the inductor leads but not the other two....should i have continuity all the way around?


Clayford

The inductor and it's traces are the first place to start looking, and it depends on which pins are continuous and which ones aren't. They usually have continuity in matching pairs
1 - 2
3 - 4

1&2 have continuity as well as 3&4
or
1&3 and 2&4

Depending on which inductor you have - you might need to rotate it 90° to get some "wah"

Yeah, you might have it rotated 90 off.

Would be helpful to indicate what inductor you have if that doesn't fix it.

okay guys, i'll let you know what happens after i rotate it.

okay....so here's a picture of my inductor...i marked the two leads that have continuity together with a red marker, the other two don't have continuity....which way should this be positioned on the pcb? Or is my inductor shot?

danwelsh

okay guys.....figured it out, my inductor is shot. :(

Got my new inductor installed today.....and now i have wah effect....this is an awesome circuit :)

No continuity should have been soldered to circuit, continuity solder to the bottom 2 holes if you haven't figured it out by now in case the inductor is good.
