Hey all. I have a Wren and Cuff 60’s Fuzz. It’s a fuzz face style pedal and uses a positive ground adapter. I have a cable for it that worked fine up until recently. The issue is that it powers the pedal sometimes, but not always. It may or may not start working again if I pull the adapter and reinsert it. It works with a battery. I do not think the cable is bad, but don’t know that for certain. W&C will repair the pedal for free, even though I bought it used. The problem is I really don’t want to send it off. It’s a pretty key part of my rig for my band. Any common issues with power jacks that I might be able to see by looking closely and then fix on my own? I am reasonably handy and can solder if needed. Thanks much for any advice.
