I fitted strap locks to my LE MARQUIS beatles bass.
found changing to them no diffrent to any off my other basses. i use the same strap for both my LE MARQUIS and my Epiphone as both have the the strap post where the neck meets the body. so it easy to swap straps.
had them for over a year like this and no problems!!!
