I am actually more concerned about the power lead which is starting to wear a bit and get harder to insert. You see I use my empeg at work and home every day. So it get plugged and unplugged at least a half a dozen times every day (it comes with me to lunch as well).
This is strange. I used my Mk1 in precisely this fashion for over a year and never had any trouble with the connector. Of course, I'll have to see how the Mk2 fares over time.
Can you give us more details about the wear problems you're having?
