I have an early 90s crybaby wah that's been gathering dust. Performed surgery last night and ripped out the buffer section, added a new linear taper pot and added true bypass. MAN, what a game changer! She's back on the board after all these years and i doubt the vox reissue will be back again. Highly suggest these mods if you have one of these. I used the "black bear" pot. Spectacular. The wah is now so lively and usable anywhere in the throw.
