I my many years of working with bands and audio this has never happened. I'm not blaming it on tascam, but rather the cable I used. I was using a TSR cable 1 quarter inch in the back of the 3rd input on the tascam 32. During the end of the gig the cable would not come out. I ended up using a big to much force and it ripped the the tip of the cable, and it remained stuck in the unit. I managed to take the unit apart, and thankfully was able to remove the tip. But during the forcing of the cable out I managed to damage the the locking mechanism inside the tascam. It seems to work find, except the cables in input three do now lock or tighten in... should this be something I worry about now? or the future? or is it bad luck... thanks
