I probably touched on this a few times before but I’m struck by the huge variation in neck sizes in a particular year. And that year is the oft venerated and sought after 1959. Everybody talks about that perfect 59 neck but the truth is, I don’t know which 59 neck they think is so perfect. Right now I happen to have a lot of 59 guitars. I have three 335’s , two 355’s and a 330. These guitars and a few others I’ve measured have wildly differing neck profiles. A28950 is a very early 335-January 59 and has that baseball bat neck like a 58 on steroids. It is around .93″ measured front to back behind the first fret and is 1.03″ at the 12th. That’s big. I have a 56 Les Paul with the same measurement. A31172 is a 335 from early September, I believe, and has the 59 neck that I associate with that “59 neck”. It measures .88″ at the first fret and around .98″ at the 12th. I also have A30877 which is a 355 and has the same profile (but has a much earlier FON-probably April). Another 59 ES-355 is A31525 which measured only .82″ at the first .91″ at the 12th. I have a 335 in the same serial number ballpark with serial number A31627 which has a first fret depth of .84″ and a 12th of .93″. It’s worth noting that 335’s and 355’s don’t follow the same timeline. The 355’s got thinner much earlier in the year.
Most of us don’t get to play that many 59’s, so we tend to remember the ones we have the privilege of playing. The conventional wisdom is that a 59 has a big neck and a late 59 has a “transitional” medium neck. But as you can see, it isn’t that simple. The 59 range (at the first fret) is .83″ to .93″. That’s more range than any other year. 1960 is a good example. That same conventional wisdom says a very early 60 has a medium neck and a later one has a thin neck. That’s also generally true except that the transition comes very early in 1960. Serial A33009 is one of my all time favorites and it measures .85″ at the first fret. But just 500 numbers later is only .81″. That’s only 4 hundredths of an inch but you can certainly feel a big difference.
There is a problem using serial numbers to gauge the manufacture date, however. Especially in the case of ES-355’s which were a much lower volume seller. Factory order numbers present a little more accurate timeline. I have had a lot of 59’s from the S8xxx range and nearly all have had .88″ first fret necks. That includes the “first rack” 345’s (S8537) that have become so sought after. They are usually in the A296xx to A 299xx range. But the 59 ES-355 I mention above has a FON of S7625 but the serial is way later at A30877. So, perhaps we should be looking more closely at FONs to get a better idea of the evolution of the 59 neck. That ’59 ES-335 with the big fat .93″ neck has a 58 FON of T5490. I have been keeping a database of FONs and serial numbers and, so far, it’s not showing me much consistency in terms of features following a predictable timeline. I’d like to be able to say that big necks ended at FON S9xxx or so but it isn’t that easy. Remember FON’s go to 9999 and then start over again at 100. So, the year 1959 starts in the S66xx range and goes through S9999, restarts at S100 and ends at around S1765. In case you’re confused, read my post on FON’s here.
