## Description

Dunlop flush mount strap lock, Black.

Review: a differenza di altri straplock questi dunlop, ad eccezione delle viti che li fissano al corpo della chitarra, non hanno parti che si avvitano, sono ad incastro (infatti consiglio delle pinze per installarli); sembra una piccolezza ma questo li rende solidi e virtualmente eterni, mi è capitato in passato infatti con altri straplock che si svitassero dalla tracolla
Review: PROS * various finish options * priced in the range of other strap locks * flushmount is a nice option if your guitar can accomodate CONS * not easily reversible due to needing to drill a larger hole for the flush mount insert * requires drilling about 1/4" deeper than a standard schaller straplock * maintenance is recommended in the instructions -- cleaning with wd-40 to avoid jamming/sticking * may have difficulty using certain higher quality/thicker leather straps * error in instructions calls for drilling with a 0.400 drill bit (good luck finding one). They actually mean that you should drill with a 3/8 bit, to a depth of .400 - measured the part with calipers before I installed. DETAILS I usually use Fender/Schaller style straplocks on my guitars and have never had an issue with those, other than the nut that holds the top half to the strap can come loose - but when it does it is typically obvious before you would ever have an issue. You tighten it with a socket on one side, and an adjustable wrench holding the other side -- and it will stay tight for a long, long time. The only problem -- on an SG the strap lock is on the back, facing your stomach, and the Schallers stick out about 3/4 of an inch, and poke you in the stomach. (Or possibly worse if you like to hang your guitar more at groin height. Can I get a snare hit?) Dual design Dunlops also stick out too far, really, on the SG. I tried those first but finally came back to the Flush Mounts, and in the end I'm very glad I did. However... I'm confident that both Schaller and Dunlop make good products that work well when properly installed. But the countersunk Dunlops are a little tricky on an SG. Mine is a '61 SG reissue, for reference. Compared to a "normal" straplock - Schaller or dual purpose Dunlop -, the screws will go about 1/4" deeper. (The actual screw length is similar but they are mounted deeper due to being in the bottom of the flush mount insert.) See photo of 2 screws and consider what is flush with the guitar body and that will make sense to you. The flush mount Dunlop *seemed* genius and like it was the perfect solution. Unfortunately, the screws are so long that they will go slightly through the front of the guitar, although in a location that is covered by a plastic cover. I read on a website that on an SG you will actually hit the truss rod, but mine didn't - I was extremely careful to drill with a tiny pilot drill first, and "feel for it", gradually expanding until I had the right hole.I removed the front plate, felt for the pilot drill, finally put the screw in once I determined that it was no big deal, and filed the tip of the screw so it would be flush with the face of the guitar, then replaced the plastic cover that hides it. If you use a thick leather strap like a Levy's leather strap, you may have difficulty getting these on the strap. I have several Levys straps, and on one there was no way these would ever work. On the others, I was able to actually get it to fit ok. On the bottom edge of the guitar after drilling the 3/8" hole, I discovered Gibson had a 15/64" hole inside with a plastic anchor for the original strap button -- too big for the screw to fasten into obviously. So I had to drill that out further to 1/4", glue in a hardwood dowel, drill a pilot hole in that, and then mount the new assembly. It has worked out fabulously well, but this was more work than any other straplocks I've installed. On my SG, the other style locks sticking out was a real pain, and this is much better -- I'm glad I did it but it took a bit of extra work. UPDATE: I gigged with this as my main guitar for more than a year since these were installed. Still very happy with them - no issues. They also never come loose (unlike my schallers), never need tightening, and that goes for the "guitar-side" part and the "strap-side" part. In fact I bought another SG today (you know...GAS), and I'm about to order another set of these and install them on that guitar too!
