Title: Weener Wah II inductor question
Post by: meelertime on May 13, 2015, 06:46:33 PM
A friend of mine gave me an old Crybaby so I decided to change it to a Weener Wah II using the single side pcb etch and the old Crybaby inductor. However, looking at the pins on the inductor, I'm not sure how it should actually mount to the pcb — any ideas? In the doc it has a hole pattern for Vox, but it's only 3 pins.

The two middle pins seem to be what you want to connect with the outer ones being for mounting I guess. So, however you can wire those two pins with the inductor being stable on the board.

I think I can manage a way to mount it - thanks for the info. One other quick question: do I just use the top two (highlighted in the pic) Vox pads on the board and leave the bottom pad out?

Yup. Bottom one is strictly four mounting support.

if you have a DMM you can measure the pins for resistance.
where you get a little resistance (around 20-30Ohm) thats the pins you need to connect

Thanks, I can definitely check that. It should be the center pins I think since they both have some of the red stuff from the core soldered to them. Does it matter which pin goes where on the board? Like a pos/neg?

No it doesn't matter.

Definitely the two
Middle
Pins I highly
Recommend a joe Gavin tone tank or a whipple both are great and worth the money
