This box is an absolute piece of crap. Crosstalk, cheap parts, etc. The cheap stomp switch WILL go out. My first one came from the factory wired as a straight Y box, not A/B selectable. Where are their quality folks? The second one lasted less than 2 months. I'm not talking about high useage either. The switch just quit switching.
