Standard 'reissue', bought new around 2005 in Canada. As soon as I got home (UK) it started playing up. Level pot has a pronounced kick around the 3 o clock position, too.
I'm thinking there might be a solder fault somewhere, or the switch needs replacing.
'Mr Grumpy' says buy a new one, not sure about that. I've lost count of the pedals I've had since 1975 when I started playing. This is the only one that has gone wrong.
