I've had mine for about four years, it started cutting out. Only when I wasn't using it, just suddenly my whole rig would go silent for no apparent reason. Seeing that I use it in the front of my signal chain, and this would happen in the middle of a gig. I found (after figuring out it's the wah, I have a big pedalboard), that if I step on the wah for a second, the sound comes back. It also makes a weird pulsing sound sometimes. I can't deal with any of that crap at a gig, so I'm going wah-less except for jams or home recording sessions where it doesn't matter if it cuts out once and a while.
I just don't feel like shelling out another $100+ bucks for this effect.
