I purchased 2 of these to adapt my banana plug output amp to regular (not TRS) 1/4 speaker cables. I found that if I plug the cable all the way into the 1/4" jacks, they don't make contact. I have to pull them out a little and then they make contact. It's a pain, and not a reliable way to operate. I disassembled the jack to see if it was miswired, it didn't seem to be. The issue appears to be with the jack itself. They both have the same issue, so it wasn't a fluke.My solution will be to hack the cables together now, but that's unfortunate, since I spent REAL MONEY on these adapters so I wouldn't have to do that.I haven't tried the Pyle version of this pigtail, which is actually a few $ cheaper, but I wish I had bought those instead.
