I've had the opposite experience- that is, I greatly prefer the Dunlop StrapLoks to the Schaller Strap Locks. Besides being lower-profile (I hate the obtrusive jutting "toggles" of the Schallers, visually and ergonomically), I've had the strap-born components of those Schallers fall apart- there's very little, shallow threading between the fastening hardware- dropping the guitar, in spite of the Schaller's stirrup-like 'cups'.LOCTITE BLUE OR EVEN RED THREAD-LOCKER IS VERY, VERY HIGHLY RECOMMENDED FOR THE STRAP-MOUNTING FASTENERS OF THE SCHALLER STRAP-LOCKS!!!
I really like the Dunlop StrapLoks on my Les Paul; my only recommendation with them is, apply a dab of Teflon-gel lubricant to the bearing-surfaces with the coupling, to eliminate squeaks and squeals from ringing out audibly through your guitars body and even pickups, amp and speakers. (Whale noises!
) The same goes for the stirrup-cups on the Schaller Strap-Locks, though be careful NOT to get any on the threaded nut and body that mounts them to the strap- that's
where you definitely want some Loctite thread-locker, or your guitar WILL
inevitably, eventually take a dive.
