EMG JV52 HZ Set

I was waiting several months for this set , I wanted to put it on my DIY Jazz. Well , they came back to stock and directly ordered them . First ''problem'' : if you dont have cts size jazz bass plate , they pots dont fit , just hold this in mind . so i order a couple of those fender plates because i put cts pots on an other bass ass well , stupidly expensive , like 22e per piece . Anyways , I thought . Then I put them , wwooow I liked them so much , so clear sound , they didnt distort like the ones the set came with , perfect , and the solderless , very good idea.
Fast forward one month later, I plug the bass and the neck pick up doesnt respond. NOthing no sound , I couldnt believe it. i thought no , emgs dont fail . I connected the pup with the other pot still jack shit though the bridge was working normally . I have NEVER EVER heard of something like I contacted them to sent it back they sent there is no refund , they just going to replace them . Now they are out of stock for several months to come. I put an order and I inluded the return invoice and I ordered the JA . which was also the LAST!! I will update when I have news about my order. UN believable
