I've got a Zoom multi-effects unit with a loose input jack, and I was wondering if I could replace it with a standard guitar output jack. It's a mono jack, as far as I can tell (i.e. it only has 2 contacts), so I'm guessing that it should be possible. It looks like it has the same screw thread for attaching it, so it'll just be a question of whether or not the guitar physically fits inside the housing I guess. Has anyone had any experience doing this? I'm guessing that amp repair technicians would know a lot about this, but I don't personally know any. Thanks in advance for any help!
