I started building the Axis wah and veered off a little as i leaned about different mods and ideas. I added the output buffer nd think i did that correct, and im adding a dcjack for power, and soon a cap selector switch. One problem i have noticed it the amount of noise/distortion like a "shhhhh" noise when i dont hit a note or rock the wah. This is when i run it through my amp w stock amp distortion. I dont think i have ever noticed this before with any of my other wahs (vox 847 or 535q.). This does have most the Axix part list suggestion. Anyone have any ideas?
