I've tried all the popular strap fittings and the corresponding buttons to fit on the guitar and I have found there is a problem of connecting and disconnecting when in a hurry at a gig. Then I tried the Fender ones. So much easier, quicker and smoother to change from one bass to the other whilst at a gig or even when playing different instruments at home. The best part is that you only need a couple of the complete set of Fender strap fittings, then you can buy the buttons to fit all your guitars and basses separately at a ridiculous low price. Absolute bargain. I did not find any problems with the fitting, but just make sure that the part on the strap is fully tight otherwise it is liable to come off. I'll give you a tip. Put a drop of Thread Grip on the thread and then tighten up with pliers. Safe as houses
