Need help! Squealing

[Pasq13]

Hey all, new to building pedals. I'm building a catalinbread formula 5. I have it all assembled and I'm getting only a squeal when its on and won't pass signal when its off. No solder bridges i triple checked. Any help please?

Welcome!  Check out the sticky Debugging thread at the top of this board.  It really works.  And pictures are good too.
