Papa Posted February 2, 2022 Share Posted February 2, 2022 Hi all! Have done a search and can’t find any info re this. I have what I’m pretty sure is a ‘74 335. I’ve read that they made these with an incomplete center maple block, but can’t find any details on this design. Anyone know exactly what this short center block is all about? For example, does it begin at the neck join and extend to just below the pups? Or does it begin at the tail and extend to just above the neck pup? Or is it “floating” in the middle of the body cavity? I’ve had the pups out, but can’t tell what the architecture of the centre block is. Also, what effect does this have on the tone of these models? Just curious. I love this guitar and its tone, so it’s just curiosity that prompts my question. Thanks to all for any replies. Quote Link to comment Share on other sites More sharing options...
Grog Posted February 3, 2022 Share Posted February 3, 2022 I can’t say for certainty, but I have a 1974 Les Paul Signature that’s similar. The center block is “T” shaped & doesn’t go all the way to the end of the guitar. I was able to take my Wi-Fi Borescope & push it from one side to the other. It’s likely that they built all ES guitars the same way………. 1 Quote Link to comment Share on other sites More sharing options...
SteveFord Posted February 3, 2022 Share Posted February 3, 2022 Grog, I've always been interested in that model. What's your take on it? Quote Link to comment Share on other sites More sharing options...
jdgm Posted February 3, 2022 Share Posted February 3, 2022 God I love that guitar. I so want a sunburst one before I die. Quote Link to comment Share on other sites More sharing options...
Papa Posted February 4, 2022 Author Share Posted February 4, 2022 After much squinting and neck contortions I was able to just barely see the Center block through the upper f-hole. It appears to extend from the heel of the body towards the neck, but ends just between the bridge posts and the bridge pup. There is a thin (approx 1/2”) extention of the block that continues along the back of the body to the neck. Shining a flashlight into the lower f-hole confirmed that the upper (neck side) body cavity is open from one side to the other. Given what I have read re Norlin-era Gibsons, I’m assuming this design was meant as a cost-saving measure, although a less cynical view might be that they were trying to make a lighter, more resonant instrument 😉 One would think that this design would move the guitar’s tone more towards a hollow body sound. I would think this would be a fairly subtle tone shift, and not something that would be obvious to my amateur ears. As I said above, I love this guitar’s tone and playability.

Papa Posted February 4, 2022 Author Share Posted February 4, 2022 Btw, thanks Grog for your reply, that’s a fine looking guitar you have there. Quote Link to comment Share on other sites More sharing options...

It is definitely it’s own animal, a cross between a Les Paul & an ES-335. The low impedance circuitry and pickups were designed by Bill Lawrence. It actually has a “Balanced “ 3 wire output jack to plug it into a mixing board, all of the other low impedance models of the time were only “Unbalanced” 2 wire. The earliest guitars shipped had the same pickups that were on the Les Paul Recording in cream. It has the chunkier Les Paul neck. It is fun to play……….. 1 Quote Link to comment Share on other sites More sharing options...
Grog Posted February 4, 2022 Share Posted February 4, 2022 (edited) I looked in the “Gruhn’s Guide to Vintage Guitars” & this is what it said…….. I think they worded it backwards, “Center Block extends only from tailpiece to end pin: Dec 1972-Aug 1975.” The block extends from the neck to past the tailpiece. This does at least show that during this timeframe the center block was different. Edited February 4, 2022 by Grog Quote Link to comment Share on other sites More sharing options...
Twang Gang Posted February 4, 2022 Share Posted February 4, 2022 If the block only went from the tailpiece to the endpin there wouldn't be much to attach the pickups to except the top itself. I think you are correct that it extends from the neck to the tailpiece leaving the lower bout more hollow. Quote Link to comment Share on other sites More sharing options...
Papa Posted February 4, 2022 Author Share Posted February 4, 2022 Thanks all for your replies and thoughts. In my particular 335, the full thickness center block seems to extend from the end pin to just past the bridge posts, which, yes, means the bridge pup screws are only attached to the top. I know! Crazy! I have done my best to get a photo with my iPhone inserted into the upper F-hole and a flashlight. These are the best I could get. The end pin is to the right, neck to the left. You can make out the end of the bridge pup floating in the open cavity, and if you look close you can see a bit of light at the far side of the cavity coming in from the bottom F-hole. When I’ve had the pups out before, I did notice there was a lot of empty space around the bridge pup. The neck pup, though, is nestled into a routed cavity in a solid block of wood. Makes me think there is a second short block just at the neck. I.e., two blocks, with a space between them under the bridge pup. Finally, as you can see, there seems to be two plates, upper and lower, that the centre block is sandwiched between, and these plates appear to run the full length of the body cavity, endpin to neck.

Papa Posted February 4, 2022 Author Share Posted February 4, 2022 I just changed my strings, so I’m loath to remove them at this time, but I’ll be sure to pop the pups out at next string change and get some better pictures. This has really piqued my curiosity. Thanks everyone for your input. Quote Link to comment Share on other sites More sharing options...
Papa Posted May 29 Author Share Posted May 29 Hey all, just an update and probably closure to this thread. Since my previous posts, I’ve come across a number of discussions in various forums and blogs regarding the whole center block thing, and it seems it’s known that Gibson has built 335s with less than full center blocks. There are reports of various configurations with the center block, including some that feature a partial cutout on the treble side, some that extend from the neck to the tailpiece but not all the way to the endpin, and others that, like mine, are a partial block sitting between the bridge and endpin with no block under the bridge pickup. This partial block thing seems to be most prevalent in the 70s Norlin era builds, although some folks report cutouts and other center block anomalies in their 60s era 335s. Tone-wise, some people feel the partial block build leads to less sustain and more hollow body jazziness, while others think a less than full center block has little effect on the tone and sustain. My own take on my guitar’s tone, as compared to online examples of “typical” 335 tone, is that my particular guitar is a little less sweet and bell like, a little more woody, and with only average sustain. Whether these qualities are down to the partial block or to the overall build of the guitar is hard to say, as there are so many factors affecting a guitar’s tone, right? As it is, it’s a fine guitar, very playable, and well suited to an amateur like myself. Quote Link to comment Share on other sites More sharing options...
Grog Posted May 30 Share Posted May 30 It is interesting to follow the changes made during the years, many to save money and labor time. Now with CNC machining, they likely look totally different again. About ten years ago, the Memphis factory was building ES Les Pauls. The center block was mahogany instead of maple & machined much thinner I assume to reduce weight. You would think that this would greatly reduce sustain, but they were nice sounding Les Pauls & way light! Quote Link to comment Share on other sites More sharing options...
merciful-evans Posted May 30 Share Posted May 30 Very interesting account. I'm wondering whether the shorter center block had any adverse effect at suppressing feedback. I presume not, but I don't know of course. Quote Link to comment Share on other sites More sharing options...
