I just got this cry baby mini wag pedal and have been trying it out for a day. The central pin that attaches the upper part of the pedal seems to come off after some use and I have been having to push it back in. Has anyone had this problem that can please advise?
Well, the first one I ordered just didn't work, but the seller sent me a new one that worked perfectly for the several months I had it until I sold it. I wouldn't expect Dunlop/MXR support to get you a new one anytime soon... when I had an Isobrick die on me, it took nearly two months to get a replacement.
If you bought it new if just return it. My bypass switching died within 5 minutes so that's what I did with mine. Blessing in disguise though really as I far preferred the sound of my old Hotone Bass Press!
