EB-3 Neck+Tension Rod problem

EB-3 Neck+Tension Rod problem
« on: December 15, 2009, 12:54:11 AM »
As I have discussed previously, I bought a Gibson EB-3 from a friend, the neck is broken and really needs to do a general restoration. My dad and I did this as we re-glued the neck according to its original structure carefully (as my dad has an experience for binding woods), after the re-bind of the neck, it was kept stored for more than 3 years. When I got the perfect time to fix the EB-3, installation of the strings to check the action and came out to be too high, the bridge is maxed out for adjustment and the only option left is the tension rod. I am worried about breaking the neck, and if does, I am doomed. So how do I end up with this problem? Any advice is much appreciated.

You can certainly try and improve things with the truss rod, or failing that you may need to reset the neck. I have seen basses that have had some wood removed from beneath the bridge, to allow it to be lowered further, although I would never recommend this. Other people just replace the bridge with low lying models, eg a badass, or file down the existing bridge (or saddles).
 
With regard the truss rod, they are easy to break if you apply too much force. Just use light pressure as you adjust. No need to force it
 
If you are careful, and allow a day between adjustments you will reduce the chances of any damage.
 
Heres what you should do
1) Mark the truss rod nut with a marker pen, so you know where it started from
2) Remove it entirely, and oil the threads
3) Replace the nut, tightening up to the original tension (hence the pen mark)
4) To tighten, just do a 1/4-1/2 turn at most, then leave it for a day to settle down. Repeat. You should never need to force it.
 
Can you post pictures? How much too high? What bridge does it have?

perhaps i would try to file down the bridge saddles, my EB3 bridge looks the same as what you have in your avatar. i did not manage to take photos of the bass with the string on it, but will try it after i do the filing. i feel really frustrated before. now i am full of hope! thank you sir!

EB3 bridge adjustment for low action
« Reply #3 on: December 16, 2009, 01:29:04 PM »
That is an option - I personally have had at least two old basses which came to me with an old Gibson non intonatable bar bridge with deep grooves cut it to lower the action.
 
Breaking the truss rod is not that easy if you are careful, i'd say you should definately have a play with that first. It may be a small truss rod adjustment will do a lot.
 
Let us know what happens.

Are you or your dad a luthier?  If not, it may be time to take it to one.  The problem with old Gibsons, especially those that have had busted necks is that the neck joint may have drifted loose over time.  I had an EB-3 neck reset, and getting a proper neck angle was a bit of a chore for my luthier.  He had another EB-0 to compare it with, and he was amused to find Gibson had done non-standardized work on them, even though they were from the same year.  It seems, at least to me, that Gibson used the basses as the learning area for guys who would be too green to work on the L-5s and Les Pauls, and no two are alike or even done with the attention to detail as well as the guitars.  Grinding down string placement on the old bridge is doing a short cut to avoid taking care of the real problem, which is the neck angle and probable need to reset it.  Good luck!

A pic of your repair would be nice to look at too!

I had to get the neck reset on my 1970 EB-3L cause it was angled forwards and the action was just terrible. My luthier did a good job and the bass is one of my main players now.

That was a bit of a challenge. The bad news is neither of us was a luthier, well I do not have any knowledge of that before not until I discovered about the existence of forums especially this. I did the bridge filing last week, kinda busy from work, but I will surely upload the photos this weekend.

Hey! have a great holidays guys! cheers.

Adjusting the truss would just screw things up further if there isn't an issue with the straightness of the neck...

The truss rod has nothing to do with the angle the neck is set at, so if you did manage to alter it to change the angle it would probably make the bass unplayable in terms of relief etc.

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!
