Leaky Transistor Buffer

The wah will work before the amplifier but sounds very low in volume and it sounds scratchy when the wah is rocked back and forth. The wah is fine without the buffer. In front of a fuzz face, with the fuzz face on, no sound passes Bizarre indeed. I`m going to go back to it and if I wired something wrong. Does the leakage and bias matter with the device Okay, I found part of the problem.
Leaky Transistor Buffer - schematic

I soldered in the transistor the wrong way, so, I removed it and put in a AC128. Unfortunately, I`m still having problems. There is an increase in volume but still no sound with the fuzz engaged, and it is still scratchy. I`m stumped. Ugh! Do I feel like an idiot. I realized that this is positive ground and won`t work properly in a negative ground circuit. I took it apart and rebuilt it using the proper schematic (negative ground) posted here at the beginning of this post. And, it works perfectly.
