Title: Wah mod advice
Post by: SocraticTelecaster on January 21, 2010, 06:33:41 PM
Need some wah modding advice here. I want to replace the 0.01uF cap in my Crybaby with a 0.022uF cap. The only problem is, I have a Rev.E board, and all of the instructions I am able to find are for Rev.F or later boards.

Here's a pic of a Rev.E board. I've circled what I assume is the 0.01uF cap, but I was hoping someone here can confirm for me that I am correct.

Also, I'm considering doing the mid-boost mod; which is the correct 1.5K resistor to swap out o the Rev.E board? Again, all of the instructions seem to reference the Rev.F or later boards.

No need to direct me to the stinkfoot page on Crybaby mods. I've already been there and wasn't able to find the answers I was looking for.

Much thanks,

-Travis

It's easy to figure out which 0.01uF cap is the "sweep cap". It's the one that is connected to the inductor.

Here are 2 pics of the solder side, if that helps.

Hard to tell from the pictures what is going on. Just check for continuity between the one end of that cap circled on the picture above and the inductor. I'm pretty sure that one circled must be the sweep cap but the tracks on the back side are kind of hard to follow.
