I had the same problem 5 months into mine.   Instead of getting just the switch "click",  I was hear other noises as well, and feeling it in my foot.  My pedal was falling apart, and essentially other crunching noises were happening from the frame of the pedal, or something else.  It also didn't respond well to the toeswitch.  This didn't happen all of the sudden but got progressively worse over time, and louder.   I'm not sure why it happened,  as I am generally fairly gentle with the pedal.

I took it back to GuitarCenter, they tested it, and experienced it as well, and they swapped it.  I had the extended protection plan at GC, so the swap was easy.

Hope this helps.

Hi guys,

This is a copy of something I posted in a seperate thread here:   http://line6.com/support/message/397104#397104

I had exactly the same issue. Really disconcerting crunch and clank sound when pushing the pedal switch.

*Disclaimer* Dismantling the unit and any resulting issues is/are YOUR responsibility.

I dismantled the pedal (just remove the main pivot bolt and be careful to catch the washers/nuts) and saw it had been assembled wrongly. One of the washers was in the wrong place - inside the pedal instead of outside next to the nut.

If yours is the same you might want to check this. Also make sure the nylon bushings which go through the pivot hole are seated correctly and then make sure the washers are outside of the pedal block (between it and the nut/bolt at either end).

I also have my pedal fairly tight so it only moves with gentle foot pressure. No problems since and it's lovely & smooth.

Hope this helps.

**Note to anyone unfamiliar with the workings of these pedals: Don't get anything (dust, parts, grease etc) in the circuit board holes and DON'T touch the sensors! Put everything back as soon as you're done and don't get too curious. **
