BOSS FZ-5 Fuzz Pédale dEffets

As a home guitarist with digital amp (silver line 20) the only effects I was missing were fuzz and wah.. for me that is not everyone. Because I'd read about issues between these pedals I bought a digital fuzz.. works perfectly before or after the wah, with or without the buffer on the wah.. I don't know why they don't advertise it to solve this issue. Literally fool proof.
