I've had several of these switchcraft jacks on various basses. From experience, if I didn't have to use a tunnel type jack ever again I wouldn't, this is simply because I believe they are more prone to damage because of the longer insert. I don't believe it is the manufacturers problem but rather just the nature of the beast. Obviously some basses with a side jack mount will need this type of jack but my advice is to only get one if it is necessary. If you have the option, get a standard old school jack connector, they last longer.
