Well worth the price!

Sister Ray 13.07.2025

I recently bought a used tele, and the output jack was hanging on by a couple of pubes (metric pubes, not imperial pubes), so I ordered one of these. Despite overseas shipping, it arrived quicker than I'd have got the guitar back from my local guitar centre if I'd taken it in to get it fixed. It took me about a minute to perform the actual repair - from hanging on by cobwebs, to factory-esque tightness. It cost way less than a professional repair job, and now it's in the drawer for the next time I need it. I took off a star for quality because it's "only" plastic, but this should last for years.

Having said that, it didn't work on my Starplayer TV. These do come in different sizes for metric/imperial socket sizes, but at the time of this review, Thomann only stocks the one which fits US-spec'ed guitars

Kırk yılda bir işe yarayacak bişey ama işini tam yapıyor. Jack plate'in içini ufak bir conta sayesinde sabitleyip sadece dıştaki somunun dönmesini sağlıyor,bu sayede iç kısımdaki kabloların dönüp parçalanmasını engelliyor. Taviye ederim...

Works fine

Fits Switchcraft jacks, my old Epiphone ES-335 jack and MIM strat jack. Other than the fact that it's made of plastic and maybe won't last forever, it does it's job really well!
