Parts Timeline #3: Bridges

Thursday, July 23rd, 2020

The top ABR-1 is a low profile version from a 58 ES-335. It’s bent as are most of them. They simply couldn’t handle the downward pressure from a set of 12’s with a wound G string. They were gone by the end of the year replaced with what you see at the bottom-the no wire full height ABR-1

If you take the time to learn all of the “parts timelines” that I am posting, you should be able to date any ES 335, 345 or 355 built between 1958 and 1969. After that, I’m not your guy. I get dozens of e-mails asking me to authenticate, date or appraise these guitars every week and I do my best to answer them all. The problem is that all of my knowledge is based on observation. Yes, I read everything on the internet…guitarhq site-excellent and informative with a few small errors and one glaring one about 335’s and I read Adrian Ingraham’s book-not so excellent. I took what I could from them but going through around 600 guitars over the past 15 years or so has taught me more than any book. And, by the way, I was flattered to have been asked by Tony Bacon to consult with him on the history section of his 335 book.

The ABR-1 bridge first showed up in 1953 when the first Les Paul Custom was released. It hasn’t changed much over the years although it was discontinued for a while and brought back. It was a good design from day one, allowing the player to intonate each string individually, although it was limited in that you couldn’t adjust the height of each string individually. Still works pretty well though. The ABR-1 is not without its issues and some of them were addressed by Gibson and some were not. Let’s start in 1958 since that’s when the first 335’s were issued. The neck angle on the 335 was, for reasons unknown, very shallow and required a lower profile ABR-1 to allow the action to be low enough. Good enough solution to a problem which shouldn’t have existed in the first place. It was a kind of “don’t raise the bridge, lower the river” solution. The ABR-1 was made of cheap metal that fatigued and bent easily. 90% of vintage ABR-1’s have some measure of sag in the middle. The low profile ABR-1 was much worse. Most of them simply broke in half. Remember, nobody was using light gauge strings back in the 50’s. 335’s shipped with 12’s and 13’s were common. All sets had wrapped G strings. So, the stress on the bridge was considerable and they sagged.

By late 58, enough owners complained and Gibson started issuing shaved full height bridges to replace the sagging low profile ones. At around the same time, they changed the neck angle to allow for a full height bridge. End of problem. But there were other problems. The early ABR-1 had nothing to hold the saddle in place but the string pressure. Imagine you’re playing a gig in a dark bar, on a dark stage. You break the E string and the saddle flies off. You probably don’t have to imagine too hard. It’s happened to most of us. It’s a little like losing a contact lens. You’re down on your knees in the middle of a gig trying to find the missing saddle. You can’t find it and you play the rest of the gig with 5 strings. The solution was simple, if a little inelegant. In early 1963 (could be late 62-it’s hard to pin down the date because so many have been changed) Gibson added a retaining wire to keep the saddles in place. It’s a pain to remove and a pain to reinstall if you need to, but it works. There have been ABR-1 copies that have saddles that stay in place without a wire and Gibson had one called the Nashville bridge but that’s a different post.

At some point during 1962, they switched from metal saddles to nylon. I think the reason for this was to make the strings slide more easily across the saddles when using the then popular Bigsby. They finally got around to beefing up the bridge to lessen the effect of the pressure exerted by the strings. This occurred in 1965 and, unless you have an older one and a newer one side by side, you probably won’t notice the slightly heavier design. At about the same time they added the patent number to the bottom of the unit and made the company name and the manufacturer’s mark much smaller. That maker’s mark would disappear by the late 60’s (useful for dating).

Timeline:

58: Low profile metal saddles. No wire, nickel

Late 58-early 63: Full height (some shaved in late 58), no wire, metal saddles, nickel

Late 62-early 63: Full height, no wire, nylon saddles (rare), nickel

63-early 65: Full height, wire retainer, nylon saddles, nickel

65-69: Full height, wire, nylon saddles, patent number w/makers mark. Chrome. Makers mark disappears around 69.

Gold bridges follow similar timeline with some small variation in dates.

One more odd characteristic to note. In ’65, there were 4 different versions of ABR-1 used on 335’s. There was the nickel one with Gibson in big letters on the back in nickel. The same one in chrome and the one with the patent number in both nickel (rare) and chrome. All had nylon saddles and wire retainers. The early nickel one was gone by the Spring and a few of the patent number nickel ones showed up during that period. By around May, Gibson had used up most of the nickel parts and was using chrome. There are plenty of guitars with some nickel and some chrome parts in 1965. It’s pretty easy to tell the difference once the nickel starts to tarnish but when brand new, they look pretty similar to most folks. Here’s a tip if you aren’t sure. Chrome looks blue. Nickel looks green. It’s subtle.

Covering a lot of ground with this photo. Top is patent number with the makers mark (off to the right). Below that is pat # without it in chrome. Early nickel below that -note the difference between chrome and nickel. Bottom shows the retaining wire.

There are no Rules

This ES-355 has a 66 serial number but it has a wide-nearly 1 11/16″ nut. It could be that it was a leftover from 65 as 355’s were pretty low volume sellers. No rules.

I try very hard to find consistency when discussing Gibsons from the so-called “Golden Era”. Certain rules and features seem to apply most of the time…PAFs until 62, then mixed PAFs and patents from 62-64, wide nut until mid 65, stop tails until early 65 and a whole lot of other features that follow a fairly predictable timeline. Except when they don’t.

One of the most desirable features of 58- early 65 ES models is the wide nut. We call it 1 11/16″ but it varies from just over 1 5/8″ to just over 1 11/16″ but all of them are wider than the 1 9/16″ nut that was introduced in mid 65 and has rendered mid 65’s to 1981 models less desirable to many players and that’s a really big deal. Imagine if 68’s had the wide nut (it’s a common misconception that they do). They would be the most desirable year post 64 for sure. Yes, 68’s had the trapeze and often had t-tops but those things can be changed. But you can’t make a narrow neck into a wide one without some very expensive (and invasive) surgery. Then a rule breaker shows up.

It is pretty commonly known that models like Byrdlands, L-5’s, Kessels and 355’s sold in fairly low numbers. Even with the low volume, they would generally make a “rack” of the same model (usually 35 guitars) all at once and then sit on the unfinished guitars until they had an order to fill. That’s why you sometimes see patent number pickups in a 61 guitar or some other earlier feature in a guitar with a later serial number. The guitars were simply built in one year and sold in the next year (or later). That’s how we end up with 1960 guitars with 1958 factory order numbers for example. But there are no FON’s after 61, so we have only the features to go by when we are trying to figure out what year the guitar was built (or at least started).

I recently purchased a 1966 ES-355 with a wide nut-just under 1 11/16″. It is the second 66 ES-355 I’ve encountered with that feature. That probably means that the guitar was built in early 65 (or at least the neck was carved then) and sat somewhere until an order came in some time in 66. I’m sure that a bunch of narrow nut 355’s went out in 65 and early 66 because I’ve seen plenty of them. So why did this one sit? Maybe it had a small flaw or maybe it was at the back of the pile and more newly made ones were headed out the door first. Without a time machine, it’s hard to know. The larger point is that all the rules I write about get broken time and time again and it isn’t always possible to come up with a reason. You could easily ask “was it re-necked later with a custom ordered neck?” Or maybe it was simply a custom order that specified a particular nut width. I know it wasn’t re-necked (it’s pretty easy to tell) but I suppose it could have been a custom order. Again, where did I leave the keys to the time machine.

I’ve had a similar experience with another 66. This was a 345 with honest to god Mickey Mouse ears. Left over early 60’s body? Maybe. Probably. The rule is that MM ears were gone by late 63 when they redid the jigs for making ES 335, 345 and 355 bodies. But this 345 and at least two others I’ve seen made their way out the door in 1966. So, no rule is a hard and fast rule and no feature is 100% consistent over the era of 1958 to 1969. After 1969, you’re on your own-I just don’t see enough of them to know much. Let me know if you have an oddball like these. It gives me something to write about.

A 66 should not have Mickey Mouse ear cutaways. And yet, this one does and at least two others I’ve seen do as well. There is a fair amount of inconsistency in the shape of the cutaways from 66 to 67 (pointy ear, “fox ear”, etc) but Mickeys? No. Great player too, by the way, although I’m sure it had nothing to do with the ears. If I recall, this one had early patent numbers which might have had something to do with it.
