Clipping with open wah, even at low volumes?? Please help!

I was jamming tonight, solo. Soon I started to hear this awful clipping whenever my wah went toe down. I switched amps. Same thing. Not the amp. I went from guitar>wah>amp (subtracted all other pedals). Problem solved. I went back to just the wah>MXR 10-band EQ>amp. The clipping came back.

I moved some levers around, mostly lowering higher frequencies, then eventually lowered the gain slider on the EQ. Problem seems to have stopped again, but it's getting late and I can't go too loud. I thought I could still little traces now and again of this clipping when I'd hammer a chord really hard... just a bit of rasp, and I was BELOW bedroom level.

For the most part, it seems to be gone. But... my thing is... why would this SUDDENLY start? I've been playing through this board for some time now, every day. The EQ is only a few months old, and the Wah is maybe a year old, give or take a few months (Dunlop Buddy Guy Wah). Like I said, with no other pedals, the clipping was gone and the sweep was smooth and claer like it should be. Once I re-introduced the EQ, it returned.

This has never been a problem before. I'm thinking it may be electrical. The EQ takes an 18v adapter (also brand new), and the wah has its own adapter. But they're all plugged into a power strip, that's full with other wall-warts and my pedal board main power--all plugs in it are part of my home rig. No extra stuff like lights or anything.

Does anyone know what could cause this raspy clipping to suddenly appear?

I appreciate any input.

Dunno about that, but I had a Dano EQ pedal that sounded great and worked great, then one day, it baked itself for no reason and hasn't worked since.

I seriously doubt it's some sort of impedance overload. Could be an exploding/exploded electrolytic capacitor in the MXR. Somebody posted an MXR Flanger here not too long ago that had the same problem. Or was it on another board? Anyhoo, it blew itself out, again, for no valid reason.
Granted that was an older pedal. Still, cheap components die young.
