I've only just started to use my HD500 properly, ie into my Marshall amp, after learning about the 4 Cable Method today! Previously I was just using headphones and even then I've hardly used the device from new... I'm not an advanced player at all and I haven't needed to mess around with the expression pedal, but I was using a guide to configuring the kit for 4CM which included a Wah pedal FX and a Volume pedal FX in the signal chain. I had no sound coming through the amp at all and it took me ages to realise it was because the Volume pedal was set to 0%! So I tried to use the expression pedal to switch over to Exp 2; what happened was there a fairly loud click/crack sound and the Vol/Pan FX became controllable by the pedal. (Strangely the Exp 2 light didn't turn on, it stayed on Red. When I tried it later after powering off, it did switch between the EXP 1/EXP 2 lights so I'll put that down to a random bug).

I'm fairly sure the ?Toe Switch? on the expression pedal didn't make a noise before, you just felt a dull contact being made, but like I said, I hardly ever tried it before. What it sounds like is something, either the pedal or the board cover, flexing beyond what it should and making a sudden hard noise as it springs out of shape. Its not always doing it and it happens more when my foot is more on the right side of the pedal. It also seems that the switch doesn't make contact when this happens, as if the pedal is mis-aligning with the switch?

Has anyone heard of this? I took a look back through pages of forum posts and haven't seen anything similar.

I phoned Line6 UK just after 4pm and would you believe, they close at 4pm on a Friday (nice for some...)

I also looked at when I registered the HD500 - you guessed it, the warranty (I'm assuming 1 year) ran out last week!!!

If I buy a second pedal, does that mean I won't need to ever touch the toe switch part again?

Thanks
