Looking for information about my EB3
« on: January 04, 2017, 06:41:09 PM »
Hello, I've been the happy owner of a rather knackered old EB3 since 1989 and I've always wondered about the changes that were made to it and if it came from the factory this way or was chopped about much later. From what I can gather it's either a '66 or a '69, and somebody put in a second bridge pickup and a toggle switch, and maybe replaced the other humbucker. I'm not looking for a value or anything like that, just maybe a little more info than I know already. Cheers in advance!

I'm thinking early '70s, just after the slotted headstock was discontinued & just before the mudbucker was moved closer to the center of the body. It has the plastic pickup surround. The "Tilt-O-Matic" bridge seems to still have nylon saddles, they were changed to metal saddles in '72. Check the pot codes. It should be something like 1377132. 137=CTS, 71-1971 & 32 would be the week it was produced. It looks like it was modified sometime after it left the factory, hopefully the pots are original. It could have a Custom Truss Rod Cover if it had been a special factory order, but that doesn't look like a Gibson TRC. Good Luck!

Hi, sorry to say this, but I'm afraid that is not a Gibson - rather a Gibson copy with some pretty accurate looking parts... it's a cool, funky looking bass, and if you enjoy it, please keep enjoying it. There were some very close copies in the early/mid seventies.

If you would like me to detail the things that underline this I shall... let me know - I don't want to ruin anyone's day though :(

Sure, I would love to know. I've never seen one like it and it plays beautifully although its showing signs of its age now. Thanks for responding.

There's no numbers on the pots, just says "Japan" and something that could be 'Cosmos'. The serial number on the headstock is stamped 828xxx and there are marks on the body which look like guide points if one were to attach hardware to make it a lefty or for bridge covers and string mutes. I've always had my suspicions that it was a bit of a Frankenbass, and honestly it's nice to know. Didn't even know there were fakes like this made.

Oh yes, there were lots and lots of different copies of these basses... some just took the general shape, others used very similar looking hardware - like this one - a very accurate bridge, IIRC Ibanez did produce some with similar bridges...

There are a lot of things 'wrong' with this bass - none of which are 100% proof this is not a Gibson, as things can be replaced etc, but combined these certainly point that way.

Firstly, the body wood should be mahogany - frankly this just looks too stripey for mahogany - I am no tree expert and there may be exceptions, but I've never seen this...

The logo doesn't look right - the crown inlay doesn't look right. If headstock was refinished this could explain these

The crown inlay was only on pre-slotted headstock models (1961-69). The plastic humbucker surround only on slotted headstock onwards (1970-79). No Gibson bass has both.

The truss rod cover should have two screws - again could be a modification (if you take it off there could be evidence or not)

The scratchplate is certainly wrong - could be a replacement

The control knobs should be witch hat wrong - could be replacements

Three way switch should be a 4 way varitone - could be a replacement

electronics should be CTS not Japanese

I'm trying to find a similar copy in my literature collection - nothing so far...

Thanks for the reply. I took the truss rod cover off and there is indeed a center screw hole to indicate a previous cover was there. The controls have always seemed iffy to me, too and the guts are frankly worrying to look at :? That said, I've never played another bass that feels as comfortable or as easy to get along with as this.

We can go into more detail if you want - maybe discover something.. you could take pics under the truss rod cover- in the pickup routes - inside the back cavity, back of headstock, and show the pickups themselves etc

things to look for.. truss rod nut should be a 5/16" hex nut - bridge pickup should have patent number sticker -  neck pickup itself is pretty distinctive once cover is removed and lifted out. The presence (or not) of a volute, and 'made in USA' are also telling...

1970 Rosetti Epiphone guitar catalogScan of 1970 Epiphone guitar catalogue produced by Rosetti for the UK market. Undated but most likely from mid-late 1970, this was the first UK catalogue to show the new range of Japanese (Matsumoku) Epiphone guitars. Interestingly, these pages show the Epiphone solid bodies with a single-sided Fender-style headstock layout - a feature quickly replaced with a typical two-sided Epiphone headstock almost immediately. Epiphone electric guitars: 9520, 9525; bass guitars: 9521, 9526; acoustic guitars: 6730, 6830, 6834
1971 A World of Guitars by Rosetti catalogueScan of 1971 Rosetti catalogue (UK) featuring guitars from from numerous manufacturers worldwide: guitars by Epiphone, Hagstrom, Levin, Hoyer, Egmond, Eros, Moridaira, Kiso-Suzuki, Schaller, and Tatra.
1971 Selmer guitar catalogueScan of 1971 Selmer guitar catalogue showing the range of electric and acoustic guitars distributed by the company: guitars by Gibson, Yamaha, Selmer, Hofner and Suzuki. 1960s Selmer had always placed Hofner at the front end of their catalogues, no doubt these were the better sellers - but into the 1970s Hofner were slipping somewhat and only appear at the tail end of this publication, pride of place going to Gibson, and to a lesser extent Yamaha. In fact this is the last Selmer catalogue to include the many Hofner hollow bodies (Committee, President, Senator etc) that had defined the companies output for so many years - to be replaced in the 1972 catalogue by generic solid body 'copies' of Gibson and Fender models. A number of new Gibson models are included for the first time: the SG-100 and SG-200 six string guitars and the SB-300 and SB-400 basses.
1968 Selmer guitar catalogueScan of 1968/1969 Selmer guitar catalogue (printed July 1968), showing the entire range of electric and acoustic guitars distributed by the company: guitars by Hofner, Gibson, Selmer and Giannini. Selmer were the exclusive United Kingdom distributors of Hofner and Gibson at the time, and this catalogue contains a total of 18 electric guitars, 7 bass guitars, 37 acoustics, and 2 Hawaiian guitars - all produced outside the UK and imported by Selmer, with UK prices included in guineas. This catalogue saw the (re-)introduction of the late sixties Gibson Les Paul Custom and Les Paul Standard (see page 69) and the short-lived Hofner Club 70. Other electric models include: HOFNER ELECTRICS: Committee, Verithin 66, Ambassador, President, Senator, Galaxie, HOFNER BASSES: Violin bass, Verithin bass, Senator bass, Professional bass GIBSON ELECTRICS: Barney Kessel, ES-330TD, ES-335TD, ES-345TD, ES-175D, ES-125CD, SG Standard, SG Junior, SG Special GIBSON BASSES: EB-0, EB-2, EB-3 - plus a LOT of acoustics branded Gibson, Hofner, Selmer and Giannini
1961 Hofner Colorama IHofner Colorama was the name UK distributor Selmer gave to a series of solid and semi-solid guitars built by Hofner for distribution in the UK. The construction and specifications of the guitars varied over the period of production, but by 1961 it was a totally solid, double cutaway instrument, with a set neck, translucent cherry finish, six-in-a-row headstock, and Hofner Diamond logo pickups. Available as a single or dual pickup guitar, this sngle pickup version would have been sold in mainland Europe as the Hofner 161.
1971 Commodore N25 (Matsumoku)Commodore was a brand applied to a series of guitars produced in Japan at the well-respected Matsumoku plant from the late 1960s to the mid 1970s - and sold primarily (perhaps exclusively?) in the United Kingdom. The models bearing the Commodore name were all guitars available from different distributors with different branding. Although there may have been some minor changes in appointments (specifically headstock branding) most had the same basic bodies, hardware and construction. Equivalent models to the Commodore N25 (and this is by no means an exhaustive list) include the Aria 5102T, Conrad 5102T(?), Electra 2221, Lyle 5102T, Ventura V-1001, Univox Coily - and most famously the Epiphone 5102T / Epiphone EA-250.
1960 Hofner Colorama IIThe Hofner Colorama was the name given by Selmer to a series of solid (and semi-solid) body Hofner guitars distributed in the United Kingdom between 1958 and 1965. The Colorama name actually applied to some quite different guitars over the period, but in 1960 it was a very light, semi-solid, set necked guitar with one (Colorama I) or two (Colorama II, as seen here) Toaster pickups. Although an entry-level guitar, it was very well-built, and a fine playing guitar; certainly a step up (at least in terms of craftsmanship) from many of the Colorama guitars that would follow, and a good deal of the guitars available in Britain circa 1960.
1971 Epiphone 1820 (ET-280) bassBy the end of the 1960s, a decision had been made to move Epiphone guitar production from the USA (at the Kalamazoo plant where Gibson guitars were made), to Matsumoto in Japan, creating a line of guitars and basses significantly less expensive than the USA-built models (actually less than half the price). The Matsumoku factory had been producing guitars for export for some time, but the 1820 bass (alongside a number of guitar models and the 5120 electric acoustic bass) were the first Epiphone models to be made there. These new Epiphones were based on existing Matsumoku guitars, sharing body shapes, and hardware, but the Epiphone line was somewhat upgraded, with inlaid logos and a 2x2 peghead configuration. Over the course of the 70s, the Japanese output improved dramatically, and in many ways these early 70s models are a low point for the brand. Having said this, there are a lot worse guitars out there, and as well as being historically important, the 1820 bass can certainly provide the goods when required.
1981 Gibson MarauderProduction of Bill Lawrence's Gibson Marauder began in 1974, with production peaking in 1978. But by 1980 the model was officially discontinued, though very small numbers slipped out as late as spring 1981. Over 7000 examples shipped between 1974 and 1979, and although no totals are available for 1980 and 1981, it is unlikely production reached three figures in either of these years. These final Marauders were all assembled at the Gibson Nashville plant, and had some nice features not available through the later years of production, such as a rosewood fretboard, and in this case, an opaque 'Devil Red' finish. It's a great looking and fine playing guitar!
