Hello, Newbie here to the forum...
I have a 68 or 69 Gibson EB-O #899439 that I am reconditioning... and have found that the bridge posts screws are worn near the top...causing the bridge to tip forward and mess up intonation and string height...

A good description of this can be found here:
https://www.flyguitars.com/gibson/bass/parts/bridge/#24

Do any of you guys know where I can order replacement bridge post screws?  I checked StewMac and AllParts but couldnt find anything there.

Thx very much!
Erik Thomas

You cant.  You have to improvise.

I think there is some debate if you can sandwich a Tone Pros stud screw on one.  I suspect maybe.

If you can live without the mute, if you even have one, you can use chrome allen screws (like MM and Stetsbar) and screw it down, using washers underneath to raise the bridge height if you need it off the stud inserts.  I think they are 5/16" bolts.  That will take the tilt problem and Carlton Fisk it right out of there.

I thought we had confirmation that the tonepros worked.  Didn't someone on DPII do this?

Thanks for the info.  I checked my local hardware/bolt specialist and they had nothing close...

as a short term solution, I screwed the bridge down underneath the flat part of the post, so the post is holding the bridge down rather than bridge sitting on top of post... the action is much better this way and there is no tipping forward.

OT:  My EB-0 is an interesting beast.  I bought it about a dozen years ago for about $350 advertised as "68 Gibson SG Bass" in a local shop in Michigan...

I didnt know much about it, but I liked the very deep tones that it puts out...

Turns out that my EB-0 has been heavily modded... there is an added Humbucker bridge pickup that is quite honky... and it has a selector switch added where you can toggle between or with both pickups.  The neck pickup is right next to the neck so it would appear that this is a 68 or 69 according to the serial number...I have seen 2 sources one which states 68 the other says 69.

It also has Grover Tuning pegs.  I recently changed the pots which were scratchy and it really sounds nice.

thx again

A better hardware store can hook you up with the bolts.  You may have to call around, as they are kind of a special thing.  I have one locally that carries them and I will give you the name of the company that makes them.  Sounds like a fun bass.  Keep your scratchy pots in the case.  If they are original it is good to hold onto them, or blue wash them and sell them.

Thanks eb2 and everyone...

Actually Im pretty happy with the setup on this bass, now that I have screwed the bridge under the post ledges.  The action is better...now im just fiddling with the intonation.

However, if you have a source for the bolts please let me know the name of the place and I will contact them anyhow, couldnt hurt.

Hey...if you get a second check out my bass and let me know what you think of the mods.... this is so well done, that it has me wondering if it werent a factory type setup....

the pick guard for the bridge pickup (p bass pickup?) is perfectly cut, the routing is dead on....the toggle switch appears to be stock Gibson...

so someone created a hybrid EB3 out of this, with only 2 knobs...
anyone have any thoughts on this?  thx. (sorry for the large pic)

It is an EB0, and your dating looks pretty sound.  That P pup mod is a far neater job than 99% of them but it did not come from the factory.  The lead pup is a DiMarzio, which were not made until the mid 70s.  So that would fall in with many thousands of guitars and basses that almost made it through the 1970s unscathed.  DiMarzio mania had people popping pups in everything in the late 70s.  Your toggle could very well be a Gibson switch, but those have been available in most music shops for decades, and was a popular way to mod without using a Radio Shack dpdt mini toggle.

Your mute is missing the felt holder, so if you need to lower the action some more, take it off.  That will give you a bit more to play with, but it may keep it right where you like it as it is.

Thx EB2 for all the info.  One final question:  when you say "lead pup" being Dimarzio, are you talking about the Bridge Pickup?  I thought that the neck pickup was stock Gibson original.

PS when I took the old pots off, they were dated 1972 from Gibson dating sources.  Threw them out though cause I had no idea that they could be worth anything :(

Im having a tough time keeping the bass in tune

Yes - I still say lead for the bridge pup.  Old school, like saying front and rear pickups.  The cream colored Precision bass pickup is a DiMarzio (although it could be a Schaller which was copy of the DiMarzio vibe).

Don't sweat the pots - they weren't original, and you aren't out anything unless you make a habit of selling parts.  

Odd about it going out of tune though.  For any shortcomings a Gibson bass may have, it is hard to knock them out of tune.  Are the tuners stock?  Are you getting string slip in the posts, or do you suspect the gears?  Something else?

man i tried everything, stretched the strings etc.  the tuners have a big G on the back, Grover or Gibson?  definitely not stock but hefty and nice tuners....the problem is there is very little "play" in the tuners from where you get it in tune to where its not... in other words, I twist the tuner to get it in tune and the slightest little variation puts it out of tune fast and by quite a lot...i havent experienced this to any degree of my 9 other guitars and 1 Fender bass...so im not sure what is up with the Gibson...probably should just get new tuners

Are those plastic saddles on the bridge?

yeah they ARE plastic...perhaps I should find some metal ones to swap them out?

I fixed some of the intonation and now it is about 90% there...Id like to get it closer to 95% though... but I dont expect to get it close to perfect.

 

Recent posts on vintage guitar and bass

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!
