Changes 1962

Wednesday, May 22nd, 2019

It’s a dot neck AND it’s a 62. Last of the dots were shipped in early 62. Then the blocks took over.

OK, back to the “changes” series just in time for Gibson to make a couple of big ones. It’s 1962. Men have flown into space, the young president is scaring the crap out of us with the Russians and their missiles and rock and roll is here to stay. But the dot neck 335 isn’t. Most folks equate 62 as the year of the block neck but it didn’t start that way. The first 62’s were, in fact, dot necks. You don’t see a lot of them and, while I don’t know exactly when the change was made, it seems like it had to be very early in the year-my guess is early February. Out of the hundreds of 335’s that have passed through my shop, only two 62 dot necks have been among them. Why change from dots to blocks? As I understand it, a lot of buyers were put off by the dot markers because they were associated with the cheapest guitars in the Gibson lineup and the 335, while nowhere near the top of the line, was not a cheap guitar. So, to bring in those buyers who didn’t want to appear to be playing a cheap guitar, Gibson changed the markers to small blocks. Probably cost them about 75 cents extra per guitar. They were still cheap plastic. Only the 355 got real MOP.

The ABR-1 was still the no wire type in 1962 but by the end of the year, the nylon saddles start to appear. I’ve always thought the nylon saddles showed up in 63 with the wire type bridges but I recently bought a 62 from the original owner who said he never changed the saddles and they were nylon. There is also some question about when the wire type bridge appeared. I’ve seen them on 62’s but I’ve seen no wire bridges on 63’s. Two things going on here. One, the change probably transitioned over a period of time and second, some folks are probably scavenging the no wire from a 62 and replacing it with a wire bridge and selling the no wire for big bucks.

The other big change to occur in 62 is only big in the collective mind of the collector. The venerable “Patent Applied For” pickup finally got its patent number assigned. Oddly, the number that Gibson put on the sticker wasn’t the correct patent number for the pickup. Its the patent number for the Les Paul trapeze tailpiece. Why that is has been the subject of debate for as long as I can remember. As most of you already know, the only thing that actually changed when they went from PAF to patent number pickups was the sticker (The $1000 sticker). There are 62’s with two PAFs, two patent numbers and one of each. You also start seeing pickups with no sign of any label at all. There could be a number of reasons for that. Some pickups got neglected or somebody had a 62 with one PAF and one patent and wanted to make it look like both were PAFs and if one had a PAF sticker and the other had no sticker, well, doesn’t logic dictate that they are both PAFs? No, it doesn’t and don’t be fooled by some genius who tells you that.

So, 1962 is the year of some big changes but not a year for a lot of changes. If it ain’t broke… 62’s are wonderful guitars-to me it is a real sleeper year. The neck profile is still slim but it is usually slightly larger than a 61 “blade” neck. The center block is still solid (with a few exceptions) and the ears are still Mickey Mouse. And the 335 is still great

One of each. 62 is the first year of the patent number pickup, replacing (slowly) the PAF. PAFs will still show up for years but not as frequently. The pickup didn’t change, only the sticker.

A block neck 62 with the short lived (and horrible) sideways trem. I know, it’s not connected but it’s the only photo I have. It looks pretty cool but unless it’s perfectly set up, it just goes out of tune. You could still get a Bigsby and many trem equipped 335’s had the stud bushings for a stop tail covered with the “Custom Made” plaque (which they weren’t).

 

His Royal Harness

Sunday, May 12th, 2019

This is 1959 harness. The bumblebees are the Mylar type. The black tubing was added except by the jack. Some harnesses have no insulation some do. It’s a crapshoot. These are Centralab pots-the date code is on the side on three of them. The fourth is also a Centralab but the code is on the top. Go figure.

OK, bad pun. Best I could do with the word harness. Electricity doesn’t know how old the parts are that it’s flowing through. If the values are the same, then the signal is the same. If the old parts have drifted, then the signal will change. I don’t usually measure the components in the harness when I get a guitar. If it sounds good and the pots work properly, I leave it alone. I have dropped new harnesses into a lot of guitars and I can’t say that a good new harness sounds any different than a good old one. Oddly (or, given the mindset of most of us vintage idiots, not so oddly) we will pay $1000 or more for a 58 or 59 date coded harness. I know, I’ve paid it. If you’re going to spend all that money to make your guitar right (or make your reissue closer to the real thing) you should know what’s in there.

There are four pots (you  knew that), two capacitors, a three way switch, a jack and a bunch of wire in a 335 or mono 355 harness. The pots in a 335/345/355 are 500K. There is a shielding can around three of them in a 345 and a stereo 355. The bridge pickup tone pot doesn’t get a can because it won’t fit (the pot is too close to the rim). So, don’t get your BVD’s in a bunch if your expensive 59 ES345 has only three cans. The capacitors have a value of .022uF. A 345 has the Varitone circuit-a two sided inductor (choke) and a 6 way switch with a load of resistors and capacitors (or two big multivalue chips). I’ve covered the Varitone in earlier posts so we’ll leave it alone.

Gibson used pots made by a few vendors and all the pots I’ve ever seen have a date code which is pretty useful if you don’t know what year your guitar was made. But keep in mind, a date code only shows you the oldest your guitar can be. You might find a 58 date code in a 60 guitar. You won’t find a 60 date code in a 58, however. Pot codes have 6 or 7 digits. Gibson generally used pots made by Centralab from 58 to 62. The three digit manufacturer code on a Centralab is 134. The next 3 or 4 digits are the week and the year. So a pot with the code 134832 would be the 32nd week of 1958. From 63 until 69 Gibson usually used pots made by CTS which have a 137 code. Same deal a pot with 137409 would be 9th week of 1964. Note that they added a second digit to the year in the 70’s to differentiate 60’s pots from 70’s and later. There were a few other manufacturers pots-mostly early on-that made their way into Gibsons. That’s another post.

The capacitors exert control over the tone pots. A higher number will be darker, a lower number will be brighter. The .022uF cap found in all ES non Varitone models is made by Sprague. The well known bumblebee (it has stripes, thus the name) cap was used from 1958 until around mid 1960. The Sprague “black beauty” (it’s, uh, black) was used from 1960 onward. I don’t know what they used in the 70’s. The very early ones (58 and early 59) are paper in oil type and the later ones are mylar. I don’t think it matters much except the paper in oil caps are supposedly more prone to drift. Any ES model with a shielding can used the same value cap but it was the disc type so it would fit inside the can. I’ve experimented with caps but since I usually have the tone control dimed, it doesn’t make any difference-the cap only affects the tone if the pot is backed off.

The three way switch was made by Switchcraft and is the long body type with a steel frame in a 335 and a brass frame in a 345 or 355. Brass is closer in color to gold, so that’s why they used the brass on guitars with gold hardware. The 1/4″ jack is also made by Switchcraft and is essentially the same today as it was in 1958. The wire is coaxial with a two strand braid on the outside and a cloth covered stranded wire on the inside. That about covers the “what”. The “why” is a longer story. Why 500K pots? I dunno. Why .022uF caps? Ask an electrical engineer.

Paper in oil bumblebees on the left. You can tell PIO from Mylar by the little filler at the top. The Sprague Black Beauties on the right are Mylar and don’t have the fillers.
